LPT: When you're getting a photo taken, move your elbows out slightly to look significantly slimmer

Basically you want is slight separation between your arm and your body. If your arm is blocking the contour of your body, the viewers' eyes do not know exactly how wide your body is, and the tendency is to view your body as wider than it is. This is a trick photographers often use when posing someone.

You're looking for just a very slight gap. It feels almost like a chicken wing motion and unnatural, but it looks good on camera done right. Try it out in a mirror and see for yourself.

Also stand up as straight as possible like there is a string on the BACK of your skull (keeps the neck straight) and roll your shoulders back.

This tip works for men and women.
