be dressed to kill: o que isso significa?

If you heard someone saying they're dressed to kill, what would you think? That there is a kind of clothing appropriate to kill people? Well, that is a mistake. When you're dressed to kill, you're ready to attract people sexually, you're wearing sexy clothes or elegant clothes to call attention from the opposite sex.

So you may be getting ready for a party when one of your friends comes out of her room looking like she'd dressed to kill. You say: wow I think someone's dressed to kill today. You look so sexy and classy at the same time. That's it for today guys. Take care!
