Hey ladies, so I am about to purchase a maxi dress from ASOS'S maternity range. It's a stretchy jersey fabric. But I am so confused with the sizing guide. I was a size 8-10 before pregnancy and haven't put on that much weight. But when I take my measurements bust, waist and hips it comes out more close to the size 16! I'm so confused because I have heard hubbers say ASOS clothes are sized generously. Any advice?
