what's missing in this photo?

Dilyn and I met our friends Anna and Ella (Ella is pictured with Dilyn below) for dinner. Towards the end of the night Dilyn decided to take off her pants. This smiling picture is after she won the war. In reality I think she thinks her shirt is actually a short dress so she didn't understand what the big deal was. Little does she know that I'm going to be able use this photo against her as she gets older...so, in the long run I won.
