Do be true to your own style, epecially on a first date. If you're a rock 'n' roll girl, let him see that. Just keep in mind that if you go too costumey, he'll notice your outfil more than you.
If dancing is part of the evening, Do find a sexy shoe that you can move in, with a bit of a platform or a kitten heel. But I say if you can't run in them. Don't try to dance in them.
Do make an effort not to dress like you do every day. If you're always in jeans, put on a skirt-or vice versa. For after work, surprise him by wearing something sexy with your suit.
Do think about what I call tabletop dressing if you're going out to dinner. He's going to be seeing you mostly from the waist up, so you want a fabulous neckline, gret earrings, a color that's gorgeous next to your face. Then keep it simple below the waist.
