I've noticed the change in the inseam length, too. It was always hard to find nice slacks with a long enough inseam in smaller sizes to accommodate my youthful skinniness
. Now, the inseam length on most slacks is actually too long!
I recently bought a few pair of Carlisle slacks and was shocked at the length, and out of a few dollars after paying the seamstress to hem them for me. Big change from having to let the hems out. Where were all these pants when I was younger?
