I am not even going to attempt to get into my size 10 jeans post baby. I'm dropping weight I think (I don't have scales, going by clothing) and have ordered two lots of jeans (M&S and Topshop) in a 12. The former are a little baggy, the latter I can do up but I am 'vacuum packed' and have a definite muffin top.
Who is more true to a size 12? Secretly hoping you don't say TopShop because this means I'm basically a size 14 with two not one dress sizes to drop!
