Bought some trousers from H&M. (I've put weight on and have gone from a 10 to a 12 on a good day, creeping towards a 14). The 12 was really small, I couldn't do them up, more like how my size 10s fit now. I ordered the 14, still too small. Is this normal for Hennes? The 14 looks more like an average 12. I want to order some jeans but can't bring myself to order the 16 when I really need to get my weight back down to my normal size !
