It's easy, really. I made a layer and used the lasso tool to select the basic shape of the item of clothing. Then I filled with with a solid color and changed the opacity of the layer in Layer Properties. For a see-thru fabric I used an opacity of about 75% and for the red stuff I used about 90%. Using an opacity like that lets the shape of the figure come through, like the breasts. Then if nipples show through and you don't want them to, you can just smudge them down (or out completely) Next I made another layer, added the details (like the collar and sleeve cuffs and the dark seams on the panties) again using the lasso to select the shape and filling with a solid color, and made that opactity a little higher so the color would be a bit darker and thicker, since fabric in those areas would be overlapping the fabric underneath. Then I selected certain areas like the areas where the clothing meets the skin, and the collar over the shirt, with the lasso tool, and added a drop shadow to each individual area to give the illusion of them being on the body rather than looking painted on. I would say it takes alot of practice, and it might for some, but these were the VERY first attempts I made at doing this, ever. No undos, no trial and error, I posted them just as I did them. :) Learning about layers and playing around with layer features has VASTLY improved my skills. Try playing around by opening a picture of a background like a forest, then opening a picture of someone's face that is approximately the same size and paste the face onto the forest on a new layer. Then go to Layers:Properties and type modes like Softlight, Hardlight, Dissolve... try them all so you can see what they do. And very the opacity up and down. You'll be SOOO amazed at what spectacular effects you can accomplish JUST by using two images and changing layer properties! Plus, it's really fun to see the results :) Okay, my fingers hurt so I'm taking a break. If this is confusing or anyone has any questions, just ask. And post your results in the forums, I'd love to see what other people are doing with this technique :)
