Size & Care Guide
SIZE GUIDE
Please note that our bikinis will have different fits and measurements based on their designs (aka. Priss is a micro and meant to fit like one!) - Make sure to check the product details of the bikini you're choosing for specific fit and sizing info!
P.S. Our Brazilian-style cuts are designed for a cheeky fit, and our adjustable ties/hardware allow flexible sizing.
For any sizing questions, please email us at helpimhot@kiantiswim.com
Step 1 - Measure Yourself

Measure around your chest at the fullest point of your bust with no bra.
Measure around your ribcage directly under your bust (where you would clasp your bra).
Measure around the narrowest part of your waist.
Measure around the widest part of your hips (where low-waisted pants would sit).
Measure around the widest part of your booty.

- Make sure the tape measure is parallel to the floor.
- Stand with your feet together and your body relaxed for all the measurements.
- Between sizes or like a little more wiggle room? We recommend sizing up in bottoms.

BIKINI CARE
KIANTI bikinis are meant to be worn 24/7, so make sure to look out for the suit you'd never want to bury (unless you're wearing it)...
If you're anything like us, you'll wear holes into your bikini. But have no fear, we'll always have more coming for you.
