Another simple leg pose for full body shots is the Cross Step. It is pretty easy and the only thing you need to watch out for is to make sure you don't look like you need to use the restroom!
Literally, you just cross your legs. You weight can be on your back leg or evenly distributed on both feet. Normally, I point my front leg to avoid the "I need to go to the bathroom NOW!" look
Other variations include:
*Slightly twisting your front foot in a coquettish way so you're standing on the edge of your foot (keep weight on back leg)
*Pointing both feet outward and standing evenly on both feet in a ballet-like pose
The Gothic Lolita in the middle shows a beautiful ballet-style variation of the Cross Step
This pose looks quite elegant. Try it out sometime!
