How can you get short shorts on RuneScape

To get short shorts on RuneScape, go to Varrock. When in the center of Varrock (near the fountain), go southwest a short distance to the clothes store (it's across from the general store). Right-click on Thessalia and select the option "Make-Over". Then just click on the "Legs" tab and scroll down until you see the Option "Shorts". Check the checkbox next to it and Click "Accept". And Voila! Short shorts on your character*!

*Note: only Female characters can have short shorts. If you do this with a male character, the shorts will be knee-length.
