The pants come with a six inch drop. That means if you subtract six inches from your jacket size you will determine your pant size. This means if you order a coat size of 42R the pants will be a 36. All pants are tailor adjustable, and can be let out 2 inches or taken in up to 4 inches. So those aforementioned 36W pants can adjust from 32-38.The pants also come unfinished at the bottom, so you can have them hemmed to the perfect length by a tailor or dry cleaner once you receive them.
