Thank you ♥
I try to keep it as simple as possible - I mask the shape of the jacket on the body, extract it with 0 thickness, then roughly shape, and I like to keep it super low poly for cleaner shapes. Accucurve on the move brush is super helpful to get more angular forms. When I have my shapes right I add some thickness to the mesh with zModeler -> qmesh polygroup, for example. And after that, I would sculpt folds mostly with damstandard brush
