I so love these shorts. For reference I am 57, 145lbs, with measurements 34, 29, 39. I placed my order for a large because I hate, hate, hate when shorts cut into the extra love for cookies I hold on my thighs and waist. I got worried though that I might should have ordered an xl and went to the manufacturer website to read up on their fit. They had a thing called true fit where you put in what size you wear in a specific brand blah blah blah long story short it told me my true fit was a SMALL... Needless to say Im glad I trusted my gut and kept the large, it fits great and I would definitely order more in the future.
