My size is 5'8'', 123 pounds, look sleem and usually wear size 4 for all clothes. Size M is excellent for me.
The quality of these pants is excellent, I feel good and not ht at all in them in warm gym, they are pleasant for skin, press enough to give pleasant feeling. I am very happy that I bought them!
