Quick answer: To find your dress size, measure three things with a soft tape: your bust (around the fullest part), your waist (the narrowest point) and your hips (the widest point). Match your largest measurement to the size chart below. If you fall between two sizes, size up for comfort — especially in fitted or bodycon styles.

The right size makes a dress feel made for you. Because cuts vary from brand to brand, your measurements — not the number on the label — are the most reliable guide. Here is how to measure yourself accurately and read our women's dress size chart, from XS to 5XL.

How do you measure yourself for a dress?

Wear light clothing and keep the tape snug but not tight. Stand relaxed and measure:

• Bust — around the fullest part of your chest, with the tape level across your back.
• Waist — around your natural waistline, the narrowest part of your torso, usually just above the belly button.
• Hips — around the fullest part of your hips and seat, with your feet together.

Note your largest measurement and use it to choose your size — a looser area can be taken in, but a too-small dress cannot be made bigger.

Women's dress size chart (XS to 5XL)

Measurements are in inches. To convert to centimetres, multiply by 2.54.

This chart is a general guide. Always check the specific measurements on each product page, as fit varies by style and fabric.

What if you are between two sizes?

It depends on the cut:

• Fitted, bodycon or stretch styles — size up for comfort and easy movement.
• Flowing, A-line or maxi styles — the smaller size usually works, as the silhouette is forgiving.
• Mixed measurements — choose the size that fits your largest measurement, then add a belt to define the waist.

Fit tips for a flattering finish

• Prioritise the area that is hardest to alter — the bust for fitted styles, the hips for pencil and bodycon cuts.
• Look for stretch fabrics and wrap or tie-waist designs if you are between sizes.

Frequently asked questions

How do I measure my dress size at home?

Use a soft tape to measure your bust, waist and hips, then match your largest measurement to the size chart. Keep the tape snug and level for accuracy.

Should I size up or down in a dress?

Size up for fitted, bodycon and stretch styles to stay comfortable. For flowing A-line and maxi dresses, the smaller size usually fits well.

What size is a US 12 in dress sizing?

A US 12 typically corresponds to a size Large (L) in this chart, with an approximate bust of 38 to 40 inches.

Do dress sizes vary between styles?

Yes. Fit changes with cut and fabric, so always check the measurements listed on each product page rather than relying on the label alone.

How should a dress fit?

A well-fitting dress sits smoothly without pulling at the bust, waist or hips, and lets you move, sit and breathe comfortably.
