I love the classic (original) blanks quite a bit. They are super comfortable and fit great. Getting 2 full sweat-suits for $150ish is really a great price (3 blanks w/30% off deal).
I am 5'8" and went for Medium for tops and bottoms. I took the risk of washing cold and drying on the no heat/low heat delicate setting. While they shrink very slightly, I stretch them out over my knee carefully and they're back to normal.
All of the blanks I've purchased have held up for over 2 years so they are made very well.
