Miracle!
Absolutely amazing! I have zero stretch marks on my stomach thanks to these, and I'm genetically predisposed to having them as my mum and sisters have a lot.
I bought two briefs and one band in the end and rotated using them every day from about week 14. I probably started earlier than needed but the briefs are extremely comfy so it wasn't a hassle to wear them.
My only complaint is I still got some on my hips and boobs. Please make a shorts body suit/bra for more coverage please!
