I am 9 weeks post C section. I am 10 stone 3, and a size 12. I bought a medium pair of these leggings and I was so upset when they arrived. I could hardly even fit them past my upper thigh they were that tiny. Even my sister who is a size 10-12 (and hasn’t just had a baby!) tried them on and they were very tight. Feel like I’ve completely wasted my money and I didn’t want to try and send them back because I stupidly ripped the tag off. Really disappointed with the purchase and it really put me off any more online purchases.
