If the trouser is in stock at time of ordering and you leave a note, they will accommodate the other trouser. So, say you take a 42R jacket and need a 32 pant, they will give you the 32 pant if in stock and left in notes. Unless this has changed recentlyI was requesting the jacket as a SC and not as part of a suit. Eventhough I haven't yet purchased a suit from S&M, I doubt the RTW suits will ever fit me since I'm a drop 8-10 normally bordering to 12 if I pick up training. RTW suits are drop 6.
