Skin Suit modelling for a super hero . Need some workflow

Guys I am trying to make black adam in blen

der. I have made the body But I don’t know how to make the suit .I have tried using the cloth physics with stitching but that was very laggy. Please suggest to me some workflow to make the skinsuit. Also, I am just 2 months into blender so pretty much I am a noob.THerefore i have just applied a material directly over the body and my model is looking weird. SO pls suggest me some workflow to model the suit after modeling the body.I have attached my work here.
