Swimwear Size Guide

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.

No Awkward 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.

Ready to find your perfect bikini?

Small chests are just like body types, they’re not one-size-fits-all. Different breast shapes are naturally suited to different bikini and bra styles, in the same way certain dresses, jeans or tops flatter different body shapes.

There’s no “better” shape, just the right style match. If you’re unsure what will work best for your breast shape, we’re always happy to help recommend a style, just reach out to us at info@louswim.com!

Frequently Asked Questions

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 OR JOANNE BIKINI?

The FIO and JOANNE 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)
