How to find your perfect fit:

Take measurements using soft tape measure.
Measure the fullest area of your bust, waist, & hips.
If you are in between sizes, we recommend sizing up.

Our bikinis are made cheeky, secure & tight. Perfect for the waves & an active lifestyle. 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. It does however mean longer straps & an increase in fabric by a few centimeters (see image below). Our swimwear will keep a consistent "Tai Swim" minimal cut, no matter the style or size.

Example: If you are not used to tight/sporty swimwear & usually wear a Medium in other brands not based in Hawai'i, you might be a Large in Tai Swim.

Kid's 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.
