If you're going to a restaurant, knee-length skirt with a split revealing your stocking tops, no panties, bra that enhances your assets and a blouse that makes it obvious you've done so. Basically, dress appropriately for the occasion/environment but make sure that you look "up for it". All men like slutty, especially when done tastefully - if you're from the UK, Jodie Marsh and Katie Price don't do it for me, whereas the two girls in red above look fine.
