Not leggings, they are tights and are see through if you bend down. Definitely not for the gym. In the inside is soft and warm so they could work in the cold months with a dress but definitely not leggings and not worth $20. Lacks quality for the price
I'm not sure what makes these leggings maternity. They are very slim fitting for a S/M. I would say these fit more like a XS/S. A little disappointed that they don't withstand the 'bend over' test either.
Overall, I wouldn't recommend them but not terrible if you're in a pinch for something inexpensive.
