I had a process for making each piece of the clothing. For the shirt, sleeve and trousers, I extracted it from the base mesh and used the cloth brushes to move it around. For the top hat, I appended a cylinder and modeled it to bend/fold over itself, I then added another cylinder for the rim and combined them with Dynamesh. I then extracted the band and Dynameshed it together again. For the belt I extracted the main band, then added the bullets by making my own custom IMM brush. I then extracted the section over the bullets and belt to make it look like its all attached together. I then added details and textures to the high poly mesh, and used Zremesher to make the low poly versions of the clothing which i took into Maya.
I unwrapped the clothing on a separate texture square.
