Fit Guide

Designed to feel tight and supportive. If you prefer a less compressive feel, size up.

Standard Fit
Seamless Technology
Seamless styles adapt to your shape. If you are between sizes, choose the larger size for comfort.
Flexibility
How to Measure
1
Chest / Bust
Measure around the fullest part of your chest or bust, keeping the tape level under your arms and across your back.
2
Waist
Measure around the narrowest part of your waist, usually just above your belly button.
3
Hips
Stand with your feet together and measure around the fullest part of your hips and seat.
4
Inseam
Measure from the crotch down to your ankle bone, or use a pair of leggings that fit you well.

Fit Note: Gymshark activewear is designed for a performance fit. Compression styles will feel tighter than relaxed styles. If you are between sizes, we recommend sizing up unless you prefer a very snug fit.

All measurements are in centimeters. For best results, measure yourself over lightweight clothing or underwear. Keep the tape snug but not tight.
