Yesterday I bought a top in H&M one size bigger than normal because I'm used to their sizes being a little on the ungenerous side, plus I am in the early stages of pregnancy and feeling v fat. When I tried it on at home it was just laughable - could not have fitted me even if I was 3 sizes smaller. In a huff I tried on one of my old tops from River Island in my normal size and it fitted perfectly, so it's not as though I've suddenly ballooned.
Anyone else found this?
