I have a friend's big birthday bash coming up and I literally have nothing to wear. I've recently lost a lot of weight and everything I own is either huge or things that I've bought for summer holidays so not exactly weather appropriate. I reckon it's a jeans and top type affair but at a cool place in a city. I've hidden myself under tunics and dresses for years so don't know where to start. I have some black skinny jeans so just need the top. I'm 31, 5ft 10 and now a size 12ish with a disproportionately long body so many tops are too short. My stomach and arms are wobbly after losing weight so quite conscious of those areas. Budget is not much £20-30 preferably. Possibly up to £40 for something wow! Help me style gurus!
