These pajamas are so comfortable! They have a soft, niche/jersey feel, that’s breathable yet comfortable.

The top fit wonderfully, being a little baggy, but the shorts were a little tight in the hips. I think they’ll loosen a little bit overtime, but if you are a little bit more blessed in the hip/booty area you See full review
