The first pose I'm going to introduce is what I call the False Step. It looks sort of like you're walking, except not :P

This one is very simple. Just take a step forward from your normal standing position and freeze!
Here is a side-angle photo, which also looks great!
Some tips to keep in mind:
*Don't let your legs be too far apart! Try to keep your knees together so you are stepping straight forward. Having a gap between your legs will look a bit awkward
*Keep your step small! Remember, you're just posing, not trying to catch the last train ;D
This pose works in virtually any style, but does give a slight feeling of coy. It might look a bit out of place in a very regal and elegant outfit like Aristocratic style. For most other styles though, it is cute and a bit "street snap" feeling, which I really like!
