Style Notes: You know when you buy yourself a nice dress for an important event—a Christmas party, your friend’s wedding or perhaps a big birthday celebration—but never find another occasion to wear it again? At Who What Wear, we’re all about making the most of your wardrobe, which is why I’m making a case for rewearing the cocktail dress for more casual occasions once the special one has passed. To do this, you just need a cute flat. This could be a ballet flat, a loafer, or better yet, a slingback. This year, the ballet-flat comeback was as big as Beyoncé’s Renaissance tour (so yeah, pretty big), and this slingback Belinda flat feels like a grown-up take on the trend. It’s not as dressy as a heel, (but not as uncomfortable, either), and styling it with a smarter dress isn’t exactly something new, but it’s a tip worth noting. I could have shown you these shoes with the age-old “jeans and a cute top,” but you already know that one. This look gives you the excuse to wear that dress you love (that’s lurking in the back of your wardrobe) on Friday night, and who’s going to pass that up?
