Sizing

Britokinis Size Guide

Mix & match sizing: every top and bottom is sized separately — order the size that fits each piece best, even if they're not the same letter.

How to Measure

Use a soft measuring tape, worn snug but not tight, over just your underwear.

  • Bust: around the fullest part of your chest, straight across your back.
  • Waist: around the narrowest part of your torso, usually just above your belly button.
  • Hip: around the fullest part of your hips.

Between two sizes? Size up for more coverage and a relaxed fit, size down for a snugger, more secured fit.
