I bought a pair from H&M on the weekend - when I got home they didn't fit! I'm not too upset about it as H&M sizes are small in comparison to other shops. There's about 2inches from button to hole if you get me. Anyway, should I take them back or keep them as an insentive to get into them by spring/summer? I'm not made of money so I should take them back and get a bigger size, shouldn't I?
