Size Guide

WAHB COUTURE — Size Guide

WAHB Couture swimwear is designed with a precise, body-conscious fit. Our pieces are cut to sit exactly where they are placed — the double-lined construction holds its shape and silhouette without shifting.

How to measure

Use a soft measuring tape against bare skin. Do not pull tight — the tape should lie flat without digging in.

Bust: Measure around the fullest part of your chest, keeping the tape parallel to the ground.

Waist: Measure around the narrowest part of your natural waist, usually just above the navel.

Hips: Measure around the fullest part of your hips and seat, usually 20–23cm below your natural waist.

Fit notes by collection

Pamela · Matilda — Triangle Bikinis: The adjustable triangle top ties allow you to customise coverage and support. If you are between sizes, size up for more coverage or size down for a more minimal fit.

Giulia · Matilda — Triangle Thong Bikinis: The same adjustable triangle top as Pamela · Matilda. The thong bottom has minimal coverage by design — it fits true to size.

Sonya · Odelia — Signature Edition: The underwire cup with light padding gives a structured, firm fit. If you are between sizes, we recommend sizing up for comfort. The underwire follows your natural cup shape — this is not a padded push-up construction; it is a support construction.

WAHB Sport · Nations: Technical Lycra has a firm, compressive fit by design. If you prefer a relaxed feel, size up one. If you prefer a compressive athletic fit, size true.
