There are many names for these types of suits / tuxedos: Mandarin collar, banded collar, clergy collar, cossack collar are too name a few. Traditionally worn in China and India, they have seen quite a bit of popularity here in the US. The best part is you don't have to wear a tie! 

This particular mandarin suit comes in a beautiful herringbone tetron-rayon fabric, that is wrinkle resistant, and soft to the touch. It has a 6 button closure, flap pockets, non-vented, traditional cut flat front pants. 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.
