This Valentine’s Day, forget flowers and fatty foods, and get your hands on a boyfriend. Boyfriend blazer, that is. The little bit longer, super roomy rendition of your office essential doesn’t only go from his closet to hers, but luckily for us it goes from day to night and season to season, too.

For day, a boyfriend blazer adds the perfect touch of modern refinement to your casual around town look. Try one over a vintage tee with jeans and an eye-popping statement necklace or over a flowy tunic with leggings and ballet flats. Don’t be disheartened by the fit; even the slouchiest of blazers will keep your look crisp.

At night, a more fitted blazer with a super structured shoulder is the ultimate accessory for your skintight mini with tights and booties. The sharp silhouette will give your trendy look a classy, sophisticated vibe, but if you’re looking for edge, scrunch or roll up those sleeves and load up on the bangles.

Because the boyfriend blazer works as sensible outerwear, but stylish inner-wear, too, it’s by far the go-to piece when it comes to that awkward seasonal transition. While it’s still chilly out, layer a blazer over a chunky knit sweater and wrap yourself in a cashmere scarf or snood. When the weather starts to warm, lose the layers and slip a blazer over your favorite cotton tank for a mature twist on the basics.
