Tops Clip through Sim

Both of your tops have something wrong with weights. In place where top meet stomach your top is way different color than body part, it would lead to differences.
In uv_1 both tops have their bottom part at the same height as body part hidden under them while in 3d mesh top is lower than it, so uv_1 is wrong here and you need to retransfer it for tops or select your top bottom part and move a bit lower than body. You can't make them so tight to body too, this especially refers to tank top. They would clip with body parts this way.
In blouse you have your collar uv in bottoms uv map area, you have to move it for example between arms uv. Use this template to place it correctly
