It should be known that the girls do not always just stand in the same manner. They each have their own quirks. We asked them to stand still and look at the ground.
This is what we got first. Camryn pulling on her shorts.

We got Cam to stop pulling on her shorts...then Kristin started tugging on her shirt.

Kristin's posture is a little different than Camryn's, so we told Kristin to "suck it in". Instead she stuck it out further.

To occupy their hands, we had them make use of their pockets, but then they started looking all over creation.

Thank goodness for digital cameras. 50 shots for one good one.
