Itās important to measure your underbust correctly. Measure around your body right under your bust where the bra band sits. Ensure the tape is straight all the way around, exhale and pull firmly.
To achieve the best results with our swimwear, we recommend a snug fit (so size down if you're in between sizes). This ensures maximum support and a flattering push-up effect. The material will also stretch over time.Ā Ā

Real Women, Real Results
As someone who has struggled with body image my whole life, the little girl who decided she needed a boob job at 12 years old, who stared at her friends c cups and was always jealous how they always looked so good- GET THIS BIKINI. i have never felt so happy looking at my tatas in the mirror. im an A-small B cup with a wider chest and flat sternum and this bikini top has made me feel so sexy and happy with myself. iāve literally never been so happy in a bikini top in my entire life in my senior age of 23. if youāre considering it- please do it. you will not regret it.

I just bought Flatbaby swimmers and all I can say is oh my god. I don't know what sorcery this is, but the pair I purchased from Flat Baby.. the material and comfort is incredible. And when I look in the mirror at the side of my boobs, they don't look like a push up bikini.. my boobs look so natural and so real.... SORCERY!! My friend had bought the baby pink swimmers size XS and the cup was too small for me, so I bought S (I am a Bcup/C cup) and they were perfect. Can't wait to buy more designs and colours you've got yourself a dedicated customer forever!! š

Two words: game changer! Bikini shopping has been a nightmare for me. After 2 babies and explant surgery, my itty bittys were left deflated and everything gaped. This bikini lifts, supports and brings the girls up and in for maximum boobage, with no gaps! Holy grail!
Nienke C
Innovative and great quality! I wanted to say this is the first bikini Iāve wore that makes me look and feel this good!! The girls sit great. Your products are designed perfectly, and give the perfect push even a push-up bra canāt achieve. Really appreciate the quality and detail of the bikini material, and also the level of work that goes into the design of the bag!! Worth every penny ā¤ļø I HOPE YOUR SMALL BUSINESS CAN CONTINUE TO GROW!! Iāve already recommended your brand to many of my friends who will be expecting to order :))
Alice
I had a boob job and after kids I decided to have them out not realising Iād be left with nothing. Being flat now and a bit broader then most I have been struggling to feel feminine in a bikini. But this actually makes me look like I have some cleavage and itās top quality also. In love! š
Nina
Well where do I start. For 42 years I have never ever liked going to the beach or to the pool due to having itty bittys. I guess I just wanted to say thank you. Thank you for creating something for us girls. Instantly made me feel more confident and happy to go to the beach this summer.
Teneale R
I just wanna say I got mine today. I am a 10AA/8A and it is amazing!! Thanks so much for making these. I was suspicious at first because Iāve tried so many push up bikinis that donāt sit properly. Even the ones that claim to be for small chests donāt work for me because of my small size. But this is 10/10. The quality was also much higher than I expected. I will be back for more colours and styles when I have $$ šā¤ļø
Jodie
This is the first time Iām actually excited to wear a bikini, I bought the pink buttercup top and I canāt believe the difference it made in cleavage. I have never had swimwear that made such a noticeable difference it boosted my confidence straight away!
Felicity R
Wow, for the first time, Iām excited to flaunt my chest this summer! š Iāll definitely be buying again and highly recommend this shop to all the small-chested ladiesāitās a total game changer! š
Tania P
This swimsuit is great for girls with small chests. Normally, I donāt like wearing push-up bras because they usually leave a gap between the bra and my chest.This is my first bikini, and I absolutely love it. It makes my chest look close together and naturally shaped, which boosts my confidence a lot.
Tarika P
Finally feel comfortable in a bikini!!! Great quality too.
Olivia H
Honestly Iām shook at the boost!!! Just found my new favourite bikinis for this summer. Not sure how I have any cleavage at all but I do with the bikini top. The personalised note was super sweet and quick shipping. Love supporting small businesses. Highly recommend flat baby swim!
Venessa T
Your bikini tops really are wizardry!! I think I stared at my chest in the mirror for a good 10 minutes because I have literally *never* seen cleavage on myself before until now, haha. Thank you for supporting the āIBTCā and I hope you go far with your small business!
Gena C
I have never had bikinis that make me sit so well!! They are the most flattering bikinis I own & I cannot wait for the warmer months to hit, thank you so muchševeryone needs a pair
Ebonye M
I love it! It definitely makes a difference!!
Bella M
I just bought this swimsuit and I love it. Itās SUCH good quality and really does make my boobs look great! The business owner also hand wrote a thank you note! Really made me understand how important shopping at small businesses is š
Lottie R
Great quality and very flattering. Iāve had a bilateral mastectomy and this bikini top still gives the impression of having boobs. So happy!
Melanie R
Iām so in love with the Lily swim suit. Since dropping fair amount of weight way to quick and loosing my boobs this swim suit has made me feel confident and comfortable to go back to the beach this summer. And the before service, helping choose sizing, fast to get orders shipped. Thank you so much š
Krystal L
Very happy š My bikini came so quickly, it fits me perfectly and the push up is amazing. I donāt feel flat chested at the beach anymore and itās boosted my confidence! I also send an email enquiry which was answered so quickly even over the Christmas period. Great product great service. Canāt wait for a restock so I can buy another colour in my size šThanks flatbaby!
Milly H
Highly recommend for ittys. I am blown away by the fit, style, and quality of this brand. I absolutely love the Lily top, my flat chest (and I mean flaaaat) has never looked better in a bikini. The shipping was super fast and the extra personal touch with the card made this purchase that much better. Couldnāt be happier.
Jasmine R
Game changing for the itty bitty committee. Never have I been more excited to try swimwear on. Iāve always hated having to worry about how I looked in a bikini, but the ones I ordered from Flatbaby are have put my stresses at ease. The sizing guide provided got me initially worried about whether itād be too small, but as suggested the xs was a perfect fit. Iām glad I gave this a chance, money well spent. The material and designs are very cute.
