Ultimate Guide: Women’s Dresses Fit & Size Conversion Table (US, UK, EU)

When it comes to shopping for dresses internationally, one of the biggest challenges women face is size confusion. A US size 8 may not equal a UK size 8, and EU numbers follow yet another system. This often leads to frustrating returns or ill-fitting purchases.

That’s why we’ve created this comprehensive women’s dress size conversion and fit guide—so you can shop confidently across US, UK, and EU brands.

At Saint G, we know that the right size is just as important as the right style—because a perfect fit makes you look and feel effortlessly elegant.

Understanding Women’s Dress Sizes

Different regions use different sizing systems:

• US Dress Sizes (Numeric 0–16): Based on body measurements in inches.
• UK Dress Sizes: Run about one size larger than the US. For example, US 6 ≈ UK 10.
• EU Dress Sizes: Numbered in the 30s–40s, corresponding to bust/waist/hip measurements in centimeters.

Example: A US 8 = UK 12 = EU 40.

Women’s Dress Fit Guide

Not all dresses are cut the same way, even within the same size. Here’s how fit and fabric affect sizing:

• Slim Fit (Bodycon, Sheath): Designed to hug the body. Stretch fabrics fit true to size, non-stretch may require sizing up.
• Regular Fit (A-Line, Midi): Balanced silhouette; most forgiving in sizing.
• Relaxed Fit (Shift, Maxi, Oversized): Roomier cut; often true to size or even slightly larger.

Fabric impact on fit:

• Stretch materials (jersey, elastane): Flexible, forgiving.
• Non-stretch fabrics (cotton, linen, satin): Less give—precise measurements matter.

How to Take Correct Measurements for Dresses

For the best fit, always measure:

• Bust: Around the fullest part of the chest.
• Waist: At the narrowest point (above the belly button).
• Hips: Around the widest part (approx. 8" below waist).
• Length: From shoulder to hem (depending on style).

Pro Tip: Measure over well-fitting undergarments for accuracy.
