This weekend I saw a lovely trench coat at Mango. It was this gorgeous green (somewhere between emerald and bright teal). It was belted and hit me mid-thigh. Unfortunately the top part of the coat (it buttoned up high, no V-neck) looked rather square on me, but I'm sure it will work for other people.
I can't find it on-line, but do go take a look if you have a Mango in your neighbourhood. It's such a great colour!
