BETSEY JOHNSON SALE Take an early lunch or just call in sick today because everyone's favorite Warhol-groupie-cum-eclectic-fashionista Betsey Johnson is having a sale. Most items are chopped down 80 percent and dresses are marked as low as $60. Do not be fashionably late or you may end up fist fighting a 14-year-old for that leopard number you want so very bad. 263 W. 38th St., third fl., (212) 947-8748. 10 a.m.-8 p.m. Through Jul. 14. This is happening in all Betsey Johnson stores, not just New York.
