Let me begin by saying, these pj pants are super soft & most likely are super comfy! I always read reviews before I buy anything, as many of us do & many of the reviews for these pants said they run small, so I ordered up. One reviewer even said its Asian sizing & to really order a size up & they were soooo wrong! Im like 53 115lbs or so & I usually wear a small or medium. I ordered a large, thinking it was Asian sizing because Im a large in that sizing & I definitely shouldve ordered a small! Theyre hilariously huge for me! Not just the waist but the length is extremely long! I took a picture of them with a pair of my yoga pants to try to show you some idea of how large the large is! Im going to return these pjs for a small & maybe then theyll get a five star!
