Menswear-inspired styles are everywhere — from trouser pants to cardigans to vests. Arguably, the most popular clothing item this season is the boyfriend blazer. The oversized jacket is the perfect layering piece for fall and winter. They come in a variety of fabrics including tweed, sateen and even bedazzled designs.

If you’re wondering how to rock the blazer, don’t fret! It goes with just about everything: Pair it with trouser jeans, skinny jeans, leggings, pencil or full skirts. Accesorize it with a scarf, skinny belt or bold jewelry. And you absolutely cannot wear one without cuffing or bunching up the sleeves. You’ll add an instant edge to the entire look.

Here are a few of S&P’s faves:
