Sophie might have been a size 8 a few years ago but she definitely isn’t anymore. I also used to be an solid 8 until my mid-late 20s but in the year or two leading up to 30 my body changed (hips widened, bum and boobs grew) and I’m now a 10-12. I didn’t necessarily gain lots of weight, it was just a change in shape and I don’t think that even with strict dieting or exercise I could ever get into an 8 again, it’s just a body change. And I feel like that’s what’s happened with her. She isn’t big by any means, her shape has just matured in the last year or two. I think it happens to a lot of people around 30.
