Mine does the exact same thing. She steals my clothes and puts them together in ways I never would, like tank tops and mini skirts and MY combat boots. She's taller than me, too. T-T She looks fifteen-ish, but she's turning twelve next month.
Tank top + miniskirt + combat boots is a very, very cute outfit, by the way >.> I've worn similar, since I'm big into the badass-warrior-woman look... even though I'm apparently kitten-adorable.
