I'm a real grown-up at last! At the age of 24!
On the other hand... yesterday I was wearing yellow-and-black stripy tights, black skirt, and my supergirl t-shirt. Today I'm wearing black combat trousers (size: Age 13), and my Little Miss Giggles t-shirt (size: Age 3-4). Okay, so not all of me is grown-up.
(The Little Miss Giggles t-shirt emphasises the bits of me that are grown-up, though. And it's worth having a slightly chilly bit of stomach where there's a gap between the t-shirt and the trousers for the sake of watching software engineers drool as I walk past.)
