FAQs

How do I use BOOMBA Inserts?

Preparation is key! Before using BOOMBA inserts, make sure your skin is clean and dry. Avoid applying makeup, oils, lotions, or other body products, as these can affect the adhesive’s ability to stick properly.

Start by putting on your clothing item. Then, place the inserts inside the garment without touching the skin. Finally, scoop your breasts to your desired position and stick the insert along with your top onto your breast to secure.

How are BOOMBA inserts different?

Unlike traditional inserts, BOOMBA inserts are sticky on both sides, which means it sticks to your clothing and to your skin for extra security. Preventing nipple slips and easily staying hidden under clothing.

BOOMBA inserts require no sewing to stay in place! Just stick to your skin and to your top! They are easily interchangeable between different tops and dresses.

How many times can I use BOOMBA Inserts?

BOOMBA inserts are designed to be reusable for up to 40+ wears with proper care. To extend their lifespan, gently clean the inserts after each use and reapply the protective films right away. This helps prevent dust, lint, and other particles from sticking to the adhesive surface and ensures long-lasting performance.

Amazing brand

Boomba was so helpful in helping me choose which size bra would fit me best, and what style would be best for my wedding dress. We went back and fourth with emails until we finally got all questions answered. They were SO quick to respond and extremely kind. 10/10 I will be purchasing again!

3 Days, No slip

I wear my inserts all the time but really put them to the test over a 3 day weekend comic con. They lifted the girls perfectly and stayed put the whole weekend! They don't slip or fall, they're super easy to use, and with my sensitive skin I appreciate that there's no irritation!

Amazing

Never use normal sticky bras again after discovering these inserts. They give amazing shape and I love how you can reuse them so many more times than traditional sticky bras.

Amazing & Really Works

Best marketing and the inserts actually work and make it look so natural. I have small boobs but these inserts give me the confidence I wanted with different outfits, especially dresses and swimsuits. Major game changer. It's super sticky and can work in sweat and water. You can reuse it, after rinsing and putting the plastic covers back on to keep the stickiness. Highly recommended 10/10. You don't need an expensive and unsafe boob job ~ just get BOOMBA! :)

Saved my wedding day

My seamstress advised me not to order these as they “wouldn’t stay in place” and insisted on sewing cups into my wedding dress - the cups were terrible! Last second I had her cut them out and order Boombas instead despite her warning and I am SO glad I did. Not only did they stay snug in place for 12+ hours of photos, dancing, etc., but they made my cleavage look more flattering than I’ve ever seen it! Can’t recommend enough.

Saved my wedding dress

These inserts literally saved my wedding dress. I am a 34A, alterations at my bridal shop said there was nothing else they could do to make the top of my dress fit while maintaining the dress quality and design. I was panicked and would not accept that my only option was dress tape. I rush ordered these inserts and was amazed! Not only did my dress seem to magically fit, but i was able to move and dance all night comfortably! I genuinely don’t know what I would have done without them.

BOOBS! I never thought I had!

I am an A cup and I desperately wanted to fill out the bust of my reception dress.

I ordered a dress online that fit my hips, thighs, and waist perfectly—as I am a curvier woman, but the bust was swallowing my small chest. All the girls swear by BOOMBA, so I ordered multiple inserts and was more than satisfied by the ultra boost size A inserts. Me, my husband, and my sister cannot stop talking about how amazing my chest looks—lol. My sister texted me “omg you have boobs!” And I immediately knew which picture she was talking about.

Thank you BOOMBA for giving a girl much needed confidence on her wedding day!

Epic stick

These inserts were amazing on my wedding day. They were super sticky but not irritating, the shape and shade was perfect and they stayed where they were supposed to all night. My dress had a deep v and this was the perfect solution for both function and comfort.

my holy grail bra!

I have east west boobs, so I pretty much never get cleavage. Only time is with those sticky bras but they make me look super flat while squishing my boobs like pancakes. I wasn't sure if I would like these but boy was I surprised! Not only did they actually give me cleavage, but they made my boobs look so good even from the side. The padding surprisingly looks really natural even though its quite padded. I can't wait to wear these for my wedding!

Highly recommend
Tremendously improved fit of my wedding dress

I was happy with my wedding dress fit- though the cups were a touch too big and I had a difficult time finding something to fill them in a bit without being a whole separate sticky bra- until I found these! They stick to your outfit and hold everything up. I danced all night and they didn’t budge one bit. I agree that their recommendation for using these with clothing that is more structured and tight will make a big difference when using as well. I rush shipped these the week of my wedding and I couldn’t be happier they arrived in time!

Best bra inserts I’ve ever used

Honestly if you’re debating on getting these because of the price just do it… I’ve always had insecurities about my small chest but I’ve been using these since the summer and literally multiple people have asked me if I got a boob job. My friends asked what I use and once I told them they immediately ordered their own! They work with most tops and last a long time too!

C
Carolyn
Totally worth it!

I wore these with my bridesmaid dress for my sister's wedding and I looked fantastic!!! There is definitely a noticeable difference and others will notice (in a good way)! I kept glancing down and couldn't stop looking at how good I looked! Super versatile and love that they're reusable - so many dresses and tops I want to wear them with now! Highly recommend!

M
Macy
Perfect for my wedding dag

I wasn’t expecting these inserts to give me much support in my wedding dress as I’m a A cup, but WOW. I was shocked! Not only did they give me SOMETHING to show, but they stayed on allll day and night. And I danced and sweated a LOT. I would recommend these 100x over to every bride and every woman! Will be wearing these again and again!!

$55 Boob job!

These are sensational. I’ve never felt so confident in my bathing suit and tops. They do not budge once you put them in. Many thanks for a great product!

The best sticky bra I have ever tried.

Seriously the best sticky bra I have ever used. They were a bit pricey so it was definitely a splurge for me, but my first pair has lasted me almost a year with continuous use. Not only do they look really natural, the adhesive is also really good. I easily get irritated and these did not irritate me at all. I am on my second pair and recommend these to all my friends. If you are on the fence, I would say get them because they really made my outfits look so much better.

Gives the lift I needed!

I used these for my wedding and it gave me the perfect amount of lift! I am a 36DD and these were perfect! They stayed in place all day and didn't notice they were there! Funny thing is that I put them on around 12 p.m and at 4 p.m. I looked down and realized I didn't take off the plastic part that goes against my chest, but it stayed perfectly in place even though it was really sweaty! I wore these until 2 a.m and they were still stuck to my dress and chest without moving after tearing up the dance floor all night! 10/10 worth the money! I am allergic to adhesive but these did not irritate my skin at all! The left is before the Boomba after having alterations done and the right is with the Ultra Lift Boomba insert!

Obsessed!!!

I have tried SOOOO many sticky bras and have hated all of them! I saw ads for these inserts and finally caved. I bought the Ultra Boost and Demi Boost. I wasn’t sure if they were going to work on me because I have very small boobs but these worked wonders! All of my low cut tops fit so much better now and the double sided stick is amazing. Do not walk, RUN to buy these!!!

Best Customer Service

My package got lost but the Customer Service team was able to provide excellent assistance until I received my order. Can’t wait to wear them for my wedding!

Jennifer Mejia
AMAZING!!!

So i bought these to wear with my wedding dress. I went for my first fitting and i was so wowed and amazed how great these worked!! Easy to apply. Customer service is on point you tell them your bra size and they will tell you the cup size to buy which was a plus for me. Definitely purchase you won’t regret it.

MAGIC I tell ya!

I have been seeing these ads for a year and have held off against getting them, but finally took the plunge for my wedding since it was highly recommended by my sales. These arrived in such beautiful packaging and took around 5 days. I already bought my wedding dress and was looking for a good wedding bra. These little things literally transformed the way my dress looked, instantly it just fit my chest so much better and my cleavage looked so good (i am so jealous of all you naturally blessed girlies!!). I have since tried them in different clothes and dresses and I feel like these inserts are magic, they seriously make all my outfits look better because I have wider hips, but no boobs (pear shape) and these give me more of an hour glass shape and really help to balance my body. I love how natural the shape is under my clothes and they really DO NOT MOVE at all!! I am amazed!!!

J
Jamie
Whoa!

My daughters are members of the IBTC and especially in formal dresses where bras aren’t easily concealed, it’s apparent that they are as flat as a board. I bought them the ultras and we were all blown away! The double sided stickiness really does the trick and it’s truly amazing.

R
Rebekah
OBSESSED

These have changed my life! Got them for my wedding dress because I didn’t have enough boob to fill and oh my do they make a difference! I tried everything until I saw BOOMBA come across my instagram! Thank you thank you! Will be wearing these with everything!

Love the diversity!

Just bought my first pair of Boombas and am super excited to try it. Have not yet received it, but I just wanted to applaud the amount of shades and sizes that are offered. You don't often see sticky bras with these many shades and I am here for it.

Jayla Mae
May need a new pair soon..

I love these inserts and they are my holy grail. I originally bought it in December for my wedding in August and ended up wearing it all the time under my outfits that they probably won't last till my wedding lol. For others that are wondering, I bought these to my fitting and it made my dress feel so secure and really gave me a more balanced silhouette which I appreciated. This is really the perfect wedding bra I have been looking for since all the other ones on the market had clasps in the middle and would probably fall off if I started sweating.

Boombas or a boob job?

This was quite the splurge for me, but since it was either Boombas or a 7k boob job, I chose the former.

I didn’t have super high expectations since I usually never like anything I buy from IG, but I was actually pleasantly surprised.

They gave volume without looking fake and really brought my Small B’s to small D’s.

The first time trying them on, I was impressed by how it changed how my dress looked, it just looked like it fit me much better and just looked more proportionate to my body. When I went out with my friends, they all noticed and commented on how natural they looked. It was definitely a boost in confidence for me.

It has been 3 months since I bought my pair and I have been wearing them religiously and so far so good. Their adhesive is a bit different from ones I have tried in the past, it’s more sticky but does not leave a oily residue if you know what I am talking about. Their adhesive is lasting me pretty long so far. They just look a little nasty from all my cats fur stuck to them lol and it’s a nightmare to get it off.

I am happy with the quality of the product and will be repurchasing in the future!

bye bras

I don't think I can go back to regular bras again after trying boomba.

I used to tuck my bra straps in my bra cups but I always felt insecure as it would move around and I was worried the bra strap would come back out. These inserts are perfect because they literally give the best most natural looking boost I have ever tried. If you havent tried them yet, this is you sign to get them now! Seriously the best purchase I have made!

stays put all day

The only type of inserts I can stand wearing. This really solves the issue of them moving which is what I had issues with in the past. These stay STUCK all day and I never had to think about them or adjust them once. Very good quality.

Must have for all my outfits now!

I literally only wear BOOMBA inserts with my going out outfits now, they seriously make everything look so much better
