Honestly, these are the best scrubs ever!! I’ve boughten MANY different brands so can genuinely compare them to others! I highly recommend them. I ordered in XS and S to see which ones would fit better. The suggested measure was accurate when it told me to choose XS. But I wanted to be sure I liked the fitting so I emailed them and asked if I could return whichever one I didn’t like. They were awesome to get back to me and told me I certainly could, that they would email me a shipping label. I guess it depends how you like the scrubs to fit, but XS was perfect for me since I like them fitted. The material is so comfortable, modern, and stretchy. I’m definitely going to be ordering more and could probably even use them for them gym! lol Btw, I got the Mens Jogger Pants 901.
