Grey Gardens

Sometimes I feel as if I'm caught between dressing like a little girl (pinafores, peter pan collars, etc) and an old lady, but really what is one in their twenties supposed to wear? Stilettos and pencil skirts? Or the ubiquitous jeans and tee shirt? I'm not really concerned with dressing my age--it's much more fun to just wear clothes that make me excited to get dressed, but still I do wonder. Is there a uniform for ladies in their twenties that I missed the memo on? Oh and yes, this is my new old lady jacket. It's not vintage, but it makes me want to dress very matchy and retro and complain about kids today.
