What does "dressed to kill" mean?

Very well-dressed, looking impressively fashionable or formal. To wear clothes that make a strong, positive impact. The hyperbole is intentional - you're "dressed" so well that you metaphorically "kill" (impress) people with your appearance. It's entirely about looking exceptionally good and polished.

Natives use this phrase as a compliment about appearance and style. It's more vivid and memorable than simply "well-dressed." The dramatic imagery makes it more interesting. You'll hear it before special events, about people with strong fashion sense, or when someone is particularly polished and impressive-looking.

You attend an important client meeting looking exceptionally professional. A colleague says, "You're dressed to kill today - you look amazing!" Recognition of your polished appearance.

Your friend emerges from their room in a striking outfit for a party. You say, "Wow, you're dressed to kill! That outfit is fantastic." Enthusiastic compliment.

At an awards ceremony, someone is impeccably dressed. You might observe, "Everyone here is dressed to kill - the fashion is incredible." Recognition of collectively exceptional appearance.

• Dressed up: Less emphatic. "Dressed up" just means formal dress; "dressed to kill" emphasises the impact and excellence.
• Well-dressed: Neutral and descriptive. "Dressed to kill" is more enthusiastic and complimentary.
• Dressed to the nines: Similar meaning and era, equally positive about appearance.

• Thinking it's about violence: It's entirely metaphorical. The "kill" refers to impressiveness, not harm.
• Using it sarcastically: "Oh, you're dressed to kill in that old shirt!" sounds confusing since the phrase is always positive.
• Applying it to casual dress: Reserve it for genuinely impressive or formal outfits, not everyday clothing.

Usually predicative: "She's dressed to kill." Past: "He was dressed to kill at the wedding." Can use as description: "a dressed-to-kill outfit" though less common. Can't really use it in progressive form; it's a state, not an action. Works with various contexts: "dressed to kill for the interview," "dressed to kill at the club."

Casual and complimentary. Very common in spoken English and informal writing. Appropriate for personal contexts and fashion discussions. Enthusiastic and admiratory tone.
