These are true to size, so no need to order up or down. They fit well, and because of the lace ties at the side, you can kind oft tighten the laces to adjust the length. So far they seem pretty sturdy, but I recommend washing them in a delicates bag, just to help preserve the material. They're very comfortable, not itchy, and the waistband isn't binding.
Loved the material—like tights with lace pieces overlaid. Not itchy. I sized up, and it was too big so that was my fault and ordered another pair which haven’t come yet. I’ll regift these. I will say tho, they seemed very long (I’m 5’3) even for a size up. So fingers crossed!
