U.S. Military, Okinawa, Deadstock, Unused, M51 Over Pants, Medium Regular size, Olive Drab Trousers Shell M-1951, TALON Aluminum Zipper. The two main pockets on the top are pass-through pockets, allowing access to the pockets of the trousers worn underneath. For a Medium Regular size, I am 170cm tall and weigh 72kg, and the fit is good in terms of both width and length. I think it would be suitable for people around 165-175cm tall. You can wear it as a single layer or layer it with other clothing. These are U.S. military over pants, originally designed to be layered, so the size is large. It's in surprisingly good condition, considering it's a 70-year-old deadstock item. You don't see them often these days, and those in good condition are rare.
