first off, Lingerie. Lacy bras, stockings and garterbelts. Those are always really hot.
Second, Leather. Leather thigh highs were originally the focus of this particular like but it has since branched out into all kinds of leather clothing. Full dominatrix outfits are nice too.
Third, many of you may already know this. Eye patches, Eye patches are the fucking most awesome thing ever. Like every girl that wears an eye patch is a fucking bad ass. They make some for some really sexy women. Love the eye patch!
Of course any combination of the three is godly and I must have it.
