Tai Swim Joelle Set Fabric XS vs. L
Our Bikinis Are Super Cheeky
They'll be secure & tight, perfect for an active lifestyle in the ocean. Your suit should be snug when you first try it on so that once it's wet, you achieve a perfect water fit. We sew very skimpy. Just because the size is L, that doesn't mean substantially more coverage. Our swimwear will keep a consistent "Tai Swim" minimal cut, no matter the style or size.

Kids Swimwear & Trunks
Kids swimwear fits true to size and is based on age (years). Going with your child's age is a great place to start. Hip measurements feature the minimum and maximum stretch for bikini bottoms and boardshorts. In-between sizes should size up. All kids swimwear and trunks feature many places for adjusting and can stretch with your child as they grow.
