The cut, length, and desired look are what matter most. A tailored blazer appears more classic, while a loose cut looks more modern and casual. The length also changes the silhouette: longer styles look particularly good worn open or can be cinched at the waist with a belt.

A blazer should fit well across the shoulders and offer sufficient freedom of movement. Depending on the cut, it can be intentionally looser around the body. With modern blazers, a relaxed silhouette is often part of the look—therefore, the deciding factor is less about a fixed rule and more about the desired fit.

A blazer looks particularly modern when styled in contrast: with jeans instead of classic dress trousers, with a shirt or sweatshirt instead of a blouse, and with sneakers or boots. Pushing up the sleeves or wearing the blazer open also makes the look more relaxed.

Clean cuts and calmer colors are particularly easy to style for the office. In everyday life, blazers can have a looser fit and feature more eye-catching colors or details. Many modern women's blazers work for both – the key is primarily the combination.

Brown harmonizes particularly well with cream, beige, white, black, gray, and denim. The look becomes more exciting with bold contrast colors. At YunaC, for example, the warm chestnut brown meets pink – a combination that makes the classic blazer look more modern.
