Size Guide

Our apparel runs true to size. If you are between two sizes, size up for a relaxed fit or stay with the smaller size for a closer one.

Please measure before you order. Every BECCA Q piece is made to order, so we are not able to accept returns or exchanges for sizing. If you are unsure, email us first — we would much rather help you get it right than have you receive something that doesn't fit.

Sports bras

Our bras are sized XS–XL and follow the bust measurements above. For high-impact training, choose the size that matches your underbust measurement most closely.

Headwear and accessories

Caps and headbands come in one size with an adjustable or elasticated fit, designed for a head circumference of roughly 54–60 cm.

How to measure

• Bust — measure around the fullest part of your chest, keeping the tape level.
• Waist — measure around the narrowest part of your torso, usually just above the navel.
• Hip — measure around the fullest part of your hips, about 20 cm below the waist.

Keep the tape snug but not tight, and measure over bare skin or light clothing.
