Affordable, Edgy, and Online-Only — But What About the Fit?

But with a constantly rotating inventory and little consistency across collections, one key question keeps coming up:Does Nasty Gal run big or small?

Nasty Gal Sizing: Generally Runs Small, Inconsistent Across Fabrics

Nasty Gal uses fast-fashion manufacturing cycles and multiple suppliers, which means sizing can vary widely between garments. Most fitted items — like dresses, bodysuits, and structured tops — run small, especially across the bust, hips, and waist. Meanwhile, oversized and stretchy items tend to run true to size or slightly loose.

Women’s Fit Overview

Bodycon Dresses & Two-Piece Sets: Often run small, especially in woven fabrics with no stretch.
Blazers & Coats: True to size in cut, but slimmer in the arms and shoulders — size up if layering.
Loungewear & Knitwear: Roomier and relaxed — generally true to size.
Trousers, Skirts & Shorts: High-waisted styles may feel tight at the waistband — many customers size up.
Corset Tops & Bodysuits: Designed to fit snug — expect them to run small.

Why Nasty Gal Feels Smaller Than Expected

Tighter cuts in key areas like the bust, waist, and thighs
Polyester-heavy fabrics that don’t stretch
Visual volume doesn’t equal generous fit — oversized styles often have narrow sleeve holes or cropped lengths

In other words, a puff-sleeve blouse may look oversized, but still feel tight around your arms or bust.

What to Buy from Nasty Gal

1. Going-Out Dresses

Mini and midi bodycon dresses with cut-outs, sequins, or mesh panels are Nasty Gal bestsellers. Most run small, especially with zips or stiff fabric. Size up if curvy or between sizes.

2. Blazers & Matching Trousers

These are more structured and fashion-forward than other fast fashion brands. Go true to size in wide-leg trousers, but size up in fitted blazers.

3. Loungewear & Knitwear

Relaxed cardigans, ribbed sets, and oversized joggers are true to size, often with stretch.

4. Tops & Corsets

Flattering but very fitted. Most styles run small — especially square-neck or underwired designs. Size up unless you're petite or flat-chested.
