I am rubbish at it. The rest of the year I look quite presentable (at least I like to think so), but I never know what to wear in warm weather - particularly for work, where the arctic air conditioning means I'm essentially dressing for two different climates.
I'm tall and quite slim but big norks, so no spaghetti straps, pasty skin, so don't really want to expose arms and legs (and too pale for fake tan), hate maxi dresses... Bah. Anyone else?
