I am 46 but wear a juniors size 1 or 3.  I ordered the small size and am very happy with the quality and fit.  I do however disagree with others who say they are long.  Maybe the larger sizes are long.  I certainly will not be putting these in the dryer for fear of them getting to short.  For the price these are amazing.  I have spent up to 60 bucks for yoga type pants and not been as pleased as I am with these.
