There are a few things you can do to make clothes see through in Photoshop. The first is to use the transparency filter. This will make the clothes look like they are made of glass. The second thing you can do is to use the layer mask. This will create a mask that only covers one layer of the image. You can then use the selection tool to select all of the clothing and then delete everything else from the selection. Finally, you can use the clone tool to create a copy of all of the clothing and then paste it into a new document.
