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
Never felt this confident
Initially I thought that I had purchased the wrong size in the Tori top, as I didn't get the oomph while wearing it, BUT after I figured out that I just needed to tie it better (check Louise's IG/TT videos for tips), it is AMAZING! So flattering and comfortable! I had pretty much given up on ever thinking that a bikini could give me cleavage until this. I ordered the set in black and wasn't sure if the black would be too slimming for the area I wanted to amplify but it wasn't. It really gives me confidence in being in a swimsuit - love it so much. Well-made, packaging is cute and shipping to Canada was also really fast.

TORI Top
Best thing ever
This white FIO top is the best thing I ever put on myself. It fits perfectly, and the white color compliments my skin even now when I don't have tan yet. (Still winter) Good thing they wrote to order a size up, so I took L instead of M and it's perfect. Now I want more colors!!

Ticks all the boxes
Exactly what I was looking for in bottoms!! Flattering and cheeky in the back with great coverage still in the front. Highly recommend for anyone looking for a thong bottom!

ELLIE Top
Gorgeous quality
So flattering, stunning colour, love the material. Offers a bit more butt coverage than the Hannah bottoms if that's what you're looking for ;-)

TORI Bottoms
Yes!
Tight in all the right places to accentuate your features in the best way! The fabric and craftmanship is so high quality. Can't stop, won't stop buying Lou Swim! <3

Definitely on the cheeky side!
After getting used to the way it sits on my butt (it's a bit more exposed than the full bikini coverage I am used to haha!) it's the only high-waisted bikini bottoms I've ever found to be flattering. The material feels lovely and I love that it's sustainably sourced.

TORI Top
Perfect!
My new favorite bra! I never found any bra that would fit me perfectly, until now. I was very worried at first but after i tried it on, I was blown away. I've never felt more confident and beautiful. I'll definitely buy more in the future!

Now I need one of everything
First time buyer of LOU and I am converted. Sign me up, take my money! And RIP all of my old bikinis. From the initial unboxing of the Erin Top and Bottom, to the super soft feel, high quality and fit - all amazing! Honestly wish I'd found this brand sooner. I am typically a Size 8, athletic build, so purchased Size M in the top and XS in the bottoms. Followed the size guide and it was spot on. Will be a loyal and returning customer.

True Perfection
This bra is the holy grail for smaller band measurements. It's the most true-to-size bra I've ever tried on. I am a 28C and this band fits perfectly, not too tight to need an extender, perfectly snug on the last hook. The cups are semi-shaped and trimmed with lace that has something of a secure edge that makes it more functional than decorative. I feel secure in the bra and I don't have any gaping at the lace at the top, the gore sits flat, it's THE fit. I wish there were more bras like this out there, this size market is severely underserved. I really hope more colors and styles are to come in the future!!
