"dressed to kill"

Going to a party and she's wondering what's the way.
I say "look, why don't you just wear what you'd wear everyday?"
You know, T-Shirt, you know sweatshirt,
You know, cut off shorts you know those...
Plain old everyday clothes.

She had a black dress that I remember still
But in her ordinary clothes the girl was dressed to kill.
I loved her, I loved her at first sight I suppose
And I couldn't have loved her more than in her...
Plain old everyday clothes.
