yep, same size. I'm normally a size 10-12, depending on the shop, and I got some over the bump maternity jeans from Next in a 12. I did try them on, and the 10s, and picked the 12 because of the fit in the leg (I hate tight clothes on my thighs). But I forgot about jeans stretching when you wear them and now they are really too loose, I'm having to wear them with a bump band and even then I'm always hiking them up, so much so that I tie a cord (from a pair of jogging bottoms) round the bottom of my bump because there are obviously no holes for a belt!
I wish I'd got the 10s but I'm just going to put up with it because they're comfy to sit in (without the cord!) and maybe when my bump gets bigger they'll fit better...?
