I tried to find reviews for these pants and it was harder than usual. Based on what I did learn I got the extra large when I usually wear a 7-9. They are just a tiny bit big but loose enough that they are comfy because of it. I'm an active girl and spend a lot of time outside and for those of you who are active you will LOVE the durability of this fabric. I was shocked to find out how well they were made. They look great and will last for a very long time. The company was great to deal with and the product is fantastic.
