The start of spring's the best time to indulge in manicures and pedicures. They're inexpensive - for beauty treatments - and your skin finally sees the light of day. If, however, you're saving your pennies, swing by Lulu Guinness's Bleecker Street store on Saturday for a complimentary manicure. They'll paint your nails Lulu red, or if you prefer, your lips (with lipstick, not nail polish). And if you buy anything from Lulu's store, which we can't imagine being hard given that it's spring and she's prone to the prettiest colors, you'll be entered for a chance to win a grand prize on May 1st. Call 212.367.2120 by Thursday to make your appointment. And when you're done, skip across the street for a cupcake.
