Invite to a Tea Party

I got the invite for the Volks opening reception. Yay! Now just a quick drive up to LA on that day and meet the sculpture of my SD 13 Jun, Mickey! It should be fun, and I hope some people I know also got an invite so I'm not standing in a corner by myself. I have a really nice outfit for my SD to wear (actually, she has several to choose from, I'm really bad about buying too many outfits!), but what shall I wear!? I wonder what the dress code is? Scary.
