Fits true to size. I hand-washed the first time and saw no extra dye. This is a lovely set - Cotton Pajama Set with Chevron and Boho-Inspired Prints, "Moroccan Blue"
These fit perfectly. I bought Medium-and I'm about a size 8-10 typically. They are lightweight and beautiful. I will probably wear them out and about-they look too nice to only wear as pajamas
