Get 3 good shades of whatever color you want. Here's mine:

Paste it onto your base if you need it.
1. Get a base like from GavSim and paste or draw the 3 colors on somewhere.

2. Make a new layer and call it "Dress"
3. Then zoom in and grab the dark color and draw in the shading with an one pixel brush like this:

4. Then, draw in the dress with the same color:

After that grab the light color(yes the light one not the middle) and fill the dress in:

5. NOW grab the middle color and draw in the base color but leave some of the light color as highlights like this:

6. Looks wierd right? well lock the transparency and grab the BLUR tool and make it soft brush size 17 or 19px. Make the strength 50 or so and blur it at least 3 times on the whole dress.:

7. Now, grab the SMUDGE tool with the size 13px brush and smudge until it looks kinda like this:

8. Now unlock the transparency and grab a nice dark shade of the color and draw an outline of the dress with a 1 px brush:

9. Just add something to go with it and..
10. Upload it!
