I'm 5'2" about 140 pounds, these are the best leggings I have purchase,they are just like the ones you purchase online,except the waist band,and they also sell they yoga one. I think I'm safe to say a person 185 lbs.could wear the one size as well,I have plenty of room,they go up to my boobs,with plenty of leg room. Give them a try,you won't be sorry
