I've just had a lightbulb moment and realised that short sleeved tshirts always look dreadful on me, especially with jeans. I can do skinny jeans with jumpers, or smarter tops, I look good in shorter or pencil skirts, cigarette trousers and jumpers or smarter tops. Definitely better with arms covered up, my style is very similar to that of Laura from the wit blog and all her winter clothes combinations. I just can't do a casual look, jeans, t shirt and boots looks awful, even if they are nice items and not cheap. I am 5'7" and a size 12. I've never realised the tshirt and casual clothes thing before, does this mean I'm a specific kind of style?
