There has long been a history of women incorporating pieces from men’s closets into their own wardrobe. Whether it’s a timeless, crisp, oversized button-up men’s shirt cinched at the waist with a belt, a blazer thrown over a cocktail dress or a pair of boyfriend jeans paired with ballet flats, a touch of menswear tailoring always adds polish to girly and everyday pieces. It’s a mlange, when done right, that can work for any occasion from casual weekend to black-tie functions.
