6. Make your gloss multitask. Keep a pearly white lip gloss in your desk drawer to slick not only on your lips but also on your brow bones and cheekbones as highlighter, says Pati Dubroff, an L.A.-based celebrity makeup artist. A universal hue she loves: Dior DiorKiss in Sorbet Meringue, $19.
7. Rework your hair flair. A glittery accessory adds instant glamour to any hairstyle. If you forget to bring one to work, use a brooch from your sweater.
8. Fake a gorgeous glow. Mix one part foundation with one part liquid illuminator, and then use your fingertips to massage it all over your face, says Brennan. Try American Beauty All Over Face Glow in Gold Glow, $15, and Mark Duotint in Double Rose, $6. Top it off with a dusting of a light-reflecting shimmer powder.
9. Sweeten your handshake. Since you're going to be shaking hands and mingling, mist your fragrance on your palms so that your touch will release a small amount of scent throughout the night.
10. Work a sexy updo. Starting with dry locks, tease the hair around your crown, then flip your head upside down and mist the underneath layers with hair spray, says Patrick Melville, creative director of Warren-Tricomi salons. Flip back up, then gather all of your hair — except the front section — into a loose bun and secure with bobby pins. Now mist those face-framing pieces with hair spray and use a round brush to blow dry them so they're sleek. Insert a sparkly hair accessory a few inches above one of your ears.
