This is such a comfortable set! I bought it twice! In a 1x and 2x. I would say they are true to size! The length of the pants is definitely tall girl friendly! I am 5’7” 280lbs the 1x fit great even the length was perfect! The 2x I bought was just a bit too long and the top fit great as well. I am small up top and thick at the bottom. I just wish they came in more colors!!!
