Wellenby fit guide

Find your
best fit.

Use this guide as a starting point. Every piece is different, so always check the measurements and fit notes shown on its product page.

Measure lightly.
Wear confidently.

Before you begin

How to
measure.

Use a soft tape measure over light clothing. Keep the tape level and comfortably close to the body without pulling it tight.

01Bust / chest

Measure around the fullest part, keeping the tape level and under the arms.

02Waist

Measure around the narrowest part of your natural waistline.

03Hip

Measure around the fullest part of your hips and seat.

04Inseam

For bottoms, measure the inner leg from the top of the thigh to the ankle.

Between two sizes? We suggest choosing the larger size for a little more ease. Product-page measurements remain the best guide for the exact piece.
