As kids we dressed up all the time. It was encouraged, and expected. As we grow and take on the mature responsibilities of life, we're not given the same freedom to play and dress up as before. But sometimes, like when you're invited to the launch of a new play and costumes are encouraged, we get to give our inner child room to play again.
The best thing is that I didn't have to buy a single thing. All the pieces were in my closet, and I just had to put them together in a new way. Except for the wig. That was in my costume suitcase...you know the one, the one that's filled with fun costumes pieces and dress up items. You don't have one? You really should get one - it's loads of fun!
