Soft, wearable basics with a touch of drama make up more of my wardrobe than they probably should, but the versatility is just too good to pass up. And they tend to last long past a season, which is always a testament to an excellent purchase. While my sunglasses are a relatively recent acquisition, the shoes and pants are from last fall, and the top and jacket are even older. Those are my favorite kinds of things -- the ones that follow you through the years. There's certainly something to be said for longevity.
