Absolutely love the leggings!
They are so comfortable and also helped me with girdle pain. I have yet to see final results after I am due to have my little girl. Super stretchy and looks fab with dresses or keeps me warm in winter wearing them under my work trousers.
So far no stretch marks and my belly has expanded quiet a bit on my 7th month of pregnancy! I've used the creams I ordered with it and has been lovely.
