Review on Ultimate Comfort: David Archy Jersey Cotton Pajama Set for Men's Sleep & Lounge by Damian Lousteau

I have read all the reviews. Judging by them, they seemed quite long, but their length did not exceed 30 inches. This teen is 14-15 years old, has a 30-32 inch waist, 35 inch inseam and is 6 feet tall! The bottom of the pajamas will be quite high even if I lengthen it by 1 inch. I ordered size M. I think I'll have to look into how to send them back. Please advise. Many Thanks
