Layered Clothing tutorials?

I’m looking to get into making Layered clothing for 1.0 Players in my game - (I’m using a custom Character similar to S15 to keep the R6 appeal.)

However I can’t find any accurate tutorials for 1.0 clothing / layered clothing itself - Does anyone have any suggestions as to how I can do this?
(Although I’m using R15, the movements are static as R6 is but the arms etc will be bending when using tools so I will need layered clothing to keep the smooth appeal.)

Thank you

Bump.

Does anyone have any suggestions as how I can convert clothing built in Roblox (3D blocky style) into layered clothing?
