Ery, it's crazy have size 0 models like that. Hell, I haven't been able to even find maternity clothes smaller than an 8. Are there maternity clothes that are smaller than an 8? Of the two pairs i bought, both Red Herring - same size (8) and style - the black jeans fit really nice but the blue ones keep falling down. Pre-pregnancy I was anything from a 4-8 depending on where I shopped. My hips are quite small. I want to order more, but I'm afraid I'm going to have the same problem. I'm already tired of pulling my jeans up all the time.
Leigh, I wore my regular clothes up until last week (4-6), although anything that sat on the waist was a not go, but all of my trousers that fit on my hips were fine. Last week I finally popped enough to have to get maternity jeans, although I don't fill them out yet. I had to go for under the bump because over the bump left too much material to fit under tops.
I also use femfresh. I swear buy it. I started using it when after I started working out 4-6 times a week. Just too much sweat and chlorine that I felt I needed it. Even the Boots brand works fine.
