Personally I think Sweats work only if you  give them an edgy downtown feel. I like mixing things that don't belong to create depth, like leather with silk or cashmere with sweatpants. I think that is what separates Fashion from Style, anyone can do fashion all you need is a credit card. Fashion is typically someone else's vision, wearing a Chanel suit with a Chanel shirt, shoes and bag is great but it is lacking your voice. Mix a Chanel jacket with a pair of jeans, white tshirt and converse is you wearing Chanel vs Chanel wearing you. Style should be about you not your credit card debt. Parisian Rule 101: I don't follow fashion, fashion follows me.
