True to size fit and comfortable
Excellent product. True to size fit. I very near ordered size smaller, expecting a loose fit bc I’m in a cusp between the two. So I’m quite happy that I read the description thoroughly. I’ll be ordering a couple more sets for this winter.

Sizes run small. Elastic waistband is tight.
Sizes run small. Waistband elastic very tight. Almost too tight. The material is very comfortable like a warm hug. I use them for winter sleep wear…bought two sets.🤔😊
