Spotted: Sarah Silverman and Diane Keaton wearing Dolce & Gabbana's polka dot skirt within one week from one another. Funny girl Silverman wore the skirt with a black cardigan (hello cleavage), funky striped gloves, and open-toe pumps last week at The Met's Costume Institute Gala. Keaton, on the other hand, opted to pair the skirt with a crisp white shirt, black patent belt and closed toe platforms at the 24th Annual Infinity Awards in NYC.
