I wear these shoes, although not in december, but I do have a minor justification to offer.

I'm tall.

How many styles of flat shoes are out there for women? A ballerina shoe is basically a heel without the heel. Any other kind of shoe without a heel is...well, a sneaker. And I can't wear sneakers with a miniskirt, sorry, not doing it.

Which would you rather have? Me wearing ballerina shoes or me being taller than you?
