Some studies of victorian clothes made in these days. I'm going to upload some others.
Vest and Trousers from different point of view - front, back and 3/4. The vest is a basic element in a victorian men's outift.
As for trousers, victorian men wore them just below the navel. They used to wear suspenders to keep trousers up instead of using a belt.
