Hayden One Piece

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. Contact our fit specialists at info@taiswim.co so we can help.

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 Co.

Super retro, fully reversible and high leg cut - Hayden is the trendiest bodysuit of every season. We recommend sizing down for a tighter and extra skimpy fit.
