I'm a wee bit too old to go for setting things on fire, although my inner teenager still relishes the very short skirt that's packed away somewhere

I go for what I like to think of as classy casual - the kinds of clothes that a woman my age with a youthful attitude might wear. I can get away with wearing skinny jeans, and I pair that with some kind of nice top or sweater, and heels or wedges, or boots if the weather is yucky. Some days I might put on some earrings but most days I don't bother. I don't want to stand out, but if someone notices me I want to be dressed tastefully. I prefer 1/2 or 3/4 length sleeves to help disguise my shoulders.
I wore a above the knee skirt out once and it gave me the willies for some reason. I haven't had the courage to try that again.
Dresses are usually a no go because of my upper body build. If I get them large enough to fit up top they are too big on the bottom.
