ways this can help u as a vendor

can make your "dress" in blender ( keep it low poly) uv  it

shift D and add a multires mod set it to 3 (4 more if you have the ram ;-) lol )

goto sculpt and add the wrinkles etc (could run a cloth sim here and get somewhat real wrinkles but sculpt is maybe easier deffo quicker lol )

bake the displacment maps 

your low poly dynamic will look like a WOW and sim faster and cleaner then a high poly mesh
