Swim Sizing
WHAT MAKES LOU SWIM DIFFERENT?
As a fellow IBTC member, Louise Chen understands the struggles of having a small chest in the water. Our padded swimwear are designed specifically for our IBTC girlies with small boobs so that it fits like a second skin (not like some floaties)!
As an additional guide to help you find your perfect fit, our models' measurements (bust, underbust, hips and waist) are listed on each product page they are featured in.

WHAT IS A "SMALL CHEST"?
Our swimsuits are catered to small chests which is 1-4 inch difference between your underbust and bust measurement.
E.g. 30" underbust and 31" bust (1" difference)
E.g. 28" underbust and 32" bust (4" difference)
If you are 5-6 inch difference, we recommend you sizing up one size.
E.g. 30" underbust and 36" bust (6" difference) we recommend sizing up from size S to size M.
Unfortunately our swimsuits are not flattering for chests with 7+ inch difference.
That is what makes our swimsuits so special, they are genuinely designed with the small chested women in mind.
BETWEEN SIZES? OR JUST PREFER A RELAXED FIT?
If you are between sizes (e.g. 68cm, 74cm, 80cm, 84cm, 90cm), we recommend that you size up if you prefer a relaxed fit.
If you prefer an extra snug and secure fit, you may wish to size down. We list the size that our models wear on every product page, so make sure to check them out along with their photos to see if that is the kind of fit you would like!
BUYING THE FIO BIKINI?
SHOP FIO
The FIO has a thick band with less stretch so runs a bit small. If you are towards the upper range of a size or prefer a more relaxed fit then we recommend that you size up.
XXS: 60cm band (68cm max stretch)
XS: 64cm band (74cm max stretch)
S: 67cm band (77cm max stretch)
M: 71cm band (81cm max stretch)
L: 76cm band (86cm max stretch)
XL: 81cm band (91cm max stretch)
NO MORE GAPS
How can you feel sexy in swimwear if you don’t feel comfortable in it (with gaps left, right and centre) and all you can think about is not flashing anyone at the beach…
No more oversized, deep cups that leave you with awkward gaps. Our shallower cups actually support your sexy small boobs and your dreams of feeling comfortable in your own skin.
NATURAL LIFT
Padding is like an endangered species in the swimwear industry and it shouldn’t be this way. Just like a natural makeup look for your face, our padding lets your boobs look good while still feeling like your beautiful self (and not 2 cups too large).
The sewn in padding won't shuffle around and can provide you with the sufficient support.
COMFORT FIRST
To feel sexy, you must first feel comfortable. Our seamless designs ensure smooth lines and no digging into your legs and armpits.
Our bikinis are crafted from the highest quality American REPREVE® fibres made from recycled plastic bottles transformed into flattering cuts and designs that ensure the perfect fit and leave you feeling like it’s a second skin.
Let customers speak for us
WOW
I’m 31 years old and am a 34A cup. I’ve never found a swimsuit that I like on my body. Swimsuits always make me feel like I have the body of a middle school boy. I took a chance on this swimsuit with LOW expectations (I recently ordered 8 swimsuits from Pacsun and Billabong, and none of them fit right, UGH)
I’m around 125 lbs, 5’ 4, and typically a 26 in jeans. I sized up to a medium in the bottoms after reading they run small (and so glad I did!!!)
I bought a size small in the top and probably should have sized up to a medium, but the top does have enough stretch to it that it fits and is still comfy.
I’m so grateful to find a suit that makes me not hate my body. Thank you thank you thank you!!!!! 🥹

Amazing all the way
I can't get enough of my Lou Swim bikinis! The fit is absolutely perfect, it hugs in all the right places, providing comfort and support while being super flattering on my bust. The burgundy color is out of this world, even more prettier than on the website. I own two FIO's but Mia is by far my favourite one!

love it!
I got a 26D (i have a 26in snug underbust) and definitely should have sized up to a 28C because the band isn't super stretchy, which helps with the longevity I guess. I am just going to wear it with an extender for now. I love how delicate the bra looks, I always needed to settle for boring bras but not anymore. Please keep releasing more lace designs, I love it so much! It fits super nicely as well, is comfortable and is nice quality despite the delicate design. :)
Cute!
I love the ribbed material, I wish that it was a bit more high waisted and had a bit more give in the material but it fits well and does not lose shape once it gets wet. Plus it's super cute paired with the matching top!

Incredible bikini!
I am so glad I tried Lou Swim because it’s honestly changed my life (not to be dramatic). I have never felt so confident in a bikini before! I’ve always struggled to find bikini tops that fit my small chest, but this top is honestly magical. The firm fabric and padding is amazing. Couldn’t recommend this brand enough!

Perfect!
This is my new favorite bra! It's so comfortable and I feel so beautiful and confident in it. Highly recommend! I have a 27 underbust and 32 overbust and I got a 28D. I found it to be very true to size. I will 100% purchase any bras Lou comes out with in the future

Amazing!
I absolutely love this bra. Ever since I first started wearing bras, I could never find one that fit perfectly, I’d always have a gap in the cups even though I was wearing the right size for my measurements. I’ve tried a bra from a different company that claims they make bras for small chested women, but I still had the gap issue with the cups, where as that issue is nonexistent with the Lou RIRI bra. It is so comfortable, the lace is beautiful, and the material of the bra is durable. Definitely recommend as the bra for small chests, it’s the only bra I plan to buy from now on!

I purchased these along with the Riri bra to have the full set and I'm so happy I did! The material is so soft and buttery, and the lace detail is so sexy!
