Ok, so I don't usually buy sweatpants online just because you can never tell how the sizing actually run, however based on previous reviews, I figured "what the heck, give it a try". Now, I do purchase JMS panties and love them, so I'm fairly familiar with the product name. These sweatpants are super comfy. My size is a 1X petite on most items, but decided to go up a size 2X based on reviews. Wish I had kept with my regular size 1X, so I feel these do run true to size. Neither way, I will keep the size I bought. I'm 5' 5" and the petite still ran a bit longer than usual. The material won't shrink as it's 50/50. I am 100% satisfied and highly recommend this product.
