For some reason I always see a coat I like every winter and can't resist the temptation of buying it, so I have one black knee length, one red & black longer length (issued by work), one short purple, one short black imitation fur. For the summer I have a lightweight blue coat and a waterproof (as we camp a lot). Making 6 coats.
Also, have two others which i'm about to throw out. Although, they have some wear they are my least favourite and I haven't got room! Only problem is I've got my eyes on a slate blue one I've seen!
