To remix a dress, you do not need to go so far as to wear a skirt over it and pretend it's a top, or throw a top on over and make the dress look like a skirt. I'm not knocking these methods- they just don't work for me. And since they don't work for me, I'm going to go out on a limb and assume these methods don't work for others, either. So how can you wear the same dress without making it look like you're an outfit repeater? It's all about the accessories, baby. I guarantee you that if Lizzie McGuire had a touch of ice under her cap and gown, the only thing Kate Sanders would have been calling Lizzie out for would have been her mad bling.
But seriously. When it's too hot to make an old dress look new by wearing a cardigan or blazer, don't forget: a little bit of jewelry goes a long way.
(And don't forget that a bun always looks better in person than it does in photos. Or at least I'd like to believe that is true.)
