Only Sizing: Mostly True to Size, But Slim Through the Waist and Bust
Only is a Danish brand, and its sizing tends to follow slim-cut European standards — especially in tops and tailored trousers. While jersey and casualwear are generally true to size, many shoppers find fitted items and woven fabrics run small, particularly across the bust and waist.
Women’s Fit Overview
-
Tops & Blouses: Run small if woven or buttoned — size up for bust room. Jersey styles are true to size.
-
Dresses: True to size, but snug in bodycon and satin styles — size up if in-between.
-
Denim & Trousers: Slim fit, especially in the waist and upper thigh. Size up if curvy or between sizes.
-
Jackets & Coats: True to size, but structured in the arms — size up for layering.

Why Only Fit May Feel Smaller Than Expected
Only combines Scandi minimalism with fast-fashion production, meaning you often get:
-
Slim European proportions, especially in the upper body
-
Fitted waists and narrow cuts in dresses and jeans
-
Polyester-heavy woven fabrics with little to no stretch
-
Shorter torsos and sleeves, especially on Petite-friendly pieces
If you're used to UK brands like New Look, River Island or Next, Only may feel a half-size smaller in most structured styles.

2. Structured Blouses and Button-Downs
Beautiful but fitted — often run small in the bust and arms. Size up for a breathable fit.

Only is known for well-cut denim, but most styles are snug at the waistband. Size up for comfort, especially in rigid or coated styles.
4. Wrap and Midi Dresses

Fit Tips for Buying Only
-
If it's woven, size up — most issues occur with non-stretch blouses or fitted dresses
-

-
Tops and jackets may run short in the torso, especially on taller frames
-
Stretch items are more forgiving — go true to size in tees, jersey dresses, and knits
