I'm 6 ft. tall. I wear a 31 waist jean with a 32 length. I am generally a 38 size suit coat.
I first ordered the 32 pant with the 38 jacket and had to send it back because it was far too small. I ordered the 34 pant with the 40 jacket next. The jacket was perfect. The pants had to be taken out 3/4 in. in the waist and hemmed. It fits perfect now and it's one of my favorite suits.
