Like an idiot I've bought a sleeveless dress for a wedding. I larve it, though I note it's one of their bestsellers so there will probably be a couple at the same wedding this is it. My immediate instinct is to reach for a pashmina (not that I have one - but the thought is there). There's a jacket thing in the same print but I've run out of money and will have to scratch around on eBay. What sort of shape would you go for? Match, clash?
