I probably could have fit the mediums, but I wanted something bigger just in case. I'm worried the mediums would have flt too tight around my thighs, and these have no problem staying up so I'm satisfied. These are shorter than I would like, but I got them for the gym since it's summer and even the gym is hot. I didn't want to spend a ton of money on maternity athletic wear that I'd only need for a few months, and this was a great inexpensive option.

Other reviews said these were see through, but I don't have that experience. Maybe sizing up solves that issue? I feel comfortable wearing these to the gym and walking my dog, but I would not want to wear these "out."
