I’m 160 lbs on a good day and normally wear a size medium (in Fabletics) because I like to have a lot of compression. I ordered these in a size small after ordering a different pair of leggings in size M and having to return them because they were WAY too big. I could have ordered these in a size XS and still fit in them! Anyway, these fit fine for the most part. Not as much compression as I would like. I don’t really like the feel of the material. They do seem to dry quickly though. Good luck finding the right size. I also ordered another pair of leggings in size S but they fit too little. So, again, good luck finding the right size.
