Boot. As you'll soon see by my next story upload... but they -love- stockings too, so it partially depends on whether or not they're going out~!
As for how long, they want to do it even when they're not actively paying attention to the person. Sure, you'll have their attention for an hour or two, the subject of their playful intent, but they don't want that to be the end of it - they'll put you somewhere you'll be safe, but flustered the whole time. See above!
