SEAESTA SURF BOARDSHORT + SWIMSUIT FIT GUIDE:
Boardshorts have a slim fit, with a shorter retro cut. Because Seaesta boardshorts have a slim, shorter fit, we recommend sizing up if your child isbetween sizes, has a belly or if you want some room for them to grow. The drawstring allows you to cinch them a little tighter if needed.
Swimsuits tend to run a bit snug and the high-quality fabric is very thick so it won't stretch out after a few wears. We recommend sizing up.
Rashguards have a slim fit. We recommend sizing up for extended wear.
