CHANEL LE VERNIS IN BLACK SATIN
Talk about high demand: This supershiny black nail polish was the first Chanel product to ever have a waitlist and inspired Internet bidding wars when it was released, in 2006. (At one point, a single bottle reached $140 on eBay.) It was one of the hottest trends of that year, thanks to celebrity megafan Victoria Beckham. (Available on Nordstrom – $27.00).
