A plain white tee is a wardrobe essential, and one of our go-to pieces year-round. So we decided to elevate our tee by giving it a little shine with metallic sleeves. We spotted shimmery separates on the runways at Prabal Gurung, Jason Wu, and Dolce & Gabbana, and an easy way to incorporate this trend into your everyday look is with today's DIY. Wear this top right now with some black cutoffs, or dress it up with a pencil skirt come the holidays. On Allison McNamara: H&M dress.
