My friend is doing a mini-session of my girls on Saturday. They wear uniforms all week for daycare, so I want to get them new outfits, but the problem is, they have completely opposite taste in clothes. My oldest (4 yrs) loves tutus and anything frilly, while my youngest (23 months) despises anything frilly (like, screams "NOOO" and throws it across the room - LOL)

How do you pick outfits for something special, like pictures (or Easter/Christmas)?
