If you want the trousers to be skintight, the trick is not to "drape" a layer of clay over the legs as you would think would be the logical way (like putting on a pair of actual pants)
Instead, what you want to do is to work on the edges of where the trousers material ends against the leg, and build it up and blend it in just in that area, and create the illusion of tight fabric, when in actual fact you have only added that very slight amount of clay at the edge of the trouser-skin interface
Does that make sense?
Keep it going!
