“I’m 5’2” 128 lbs and usually wear a size small. I had to return the small and get an XS in the Charlotte set. I also sized down for my daughter in law. The material is great. It washes and dries great. I haven’t noticed any shrinkage. I have the other style pj (can’t remember the name) that has elastic waistband and pull over top and it runs more true to size. I have a small and it works fine for me. I’ve also ordered the men’s pj bottoms for my sons and husband. They love them! They look forward to getting a new pair each Christmas. They are so soft I see Santa being worn year round by all of them. Too funny! I have to mention customer service…they go above and beyond to make sure you are happy. They are prompt and follow up with any request or questions about exchanges or returns. Great company all around.”
