Kind of a noob question here, but does anyone have any experience in the procedure of taking in a pair of jeans to get tapered? I have a pair of nudie bootcuts that I want to turn basically into straight leg fit. Do I just tell the tailor what size I want the hem? For reference, my jeans are 7" at the knee and 8" at the hem. I'd like it to be 7" straight down from the knee to the hem. Is this feasible for a tailor to understand and do?
