Fit, Form & Measurements

Size Guide

Use product measurements first, then compare them with your body measurements and preferred fit.

Before the chart

The product page comes first.

Our general chart is a starting point. Sizing can vary by supplier, fabric, stretch, construction, and intended fit. When a product page includes its own measurements, use those measurements before this guide.

How to measure

Three measurements shape the choice.

Wear lightweight clothing, keep the tape level, and let it rest against the body without pulling tight.

01

Bust

Measure around the fullest part of your bust and keep the tape level across your back.

02

Waist

Measure around the narrowest part of your natural waist without holding your breath.

03

Hips

Measure around the fullest part of your hips and seat while keeping your feet together.

Note

This chart is a general reference, not a guarantee of fit. Compare the garment measurements, material, stretch, and intended silhouette on the product page.

Fit guidance

Read the fabric and silhouette.

A number alone cannot tell the full fit story. These details help you choose more intentionally.

Between sizes

Choose your preferred ease.

Size up for more comfort, especially when the garment is fitted or has limited stretch.

Bodycon & fitted

Measure every key point.

Compare bust, waist, and hip measurements carefully and review the fabric’s stretch.

Relaxed & oversized

Extra room may be intentional.

Your usual size may already create the intended shape. Read product fit notes before sizing up.

Swimwear & bodysuits

Check fit and return status.

Review product-specific measurements and final-sale eligibility before ordering.

Between two sizes?

Let comfort decide.

For a closer fit, consider the smaller size when the fabric has generous stretch. For more ease, or a low-stretch fabric, consider the larger size.
