Or you could say "spiky leather boots. And thats it".

But the costume usually dictates the shoes

Sexy nurse: white patent leather over white stockings

French Maid: black patent leather over black stockings

Police/Military: black knee-high boot. usually without a spike heel. May be sold as 'riding boots' or 'motorcycle boots'

Bunny Girl: WTF is a bunny girl?

School Girl (both naughty & nice varieties): knee high socks and mary janes (asian schoolgirl = knee high socks & the most garishly colored snealers you can find)

Punk Grrl: lace-up boots (traditionally black Dr. Martens) over fishnet stockings

Miss Whiplash: black leather (regular or patent), spiky heel is required for use in trampling and/or oral worship. Boots and shoes both have precedent, stockings optional (but only in black or fishnet).

Not long, mini's so you could just hike them up and do your buisness.
Thats Hot!
