Black seems to be back in style, and Nicky Hilton is not the only star who has been spotted out and about in more sombre shades than her sister. According to Hello Magazine, Paris Hilton's younger sister and singer Avril Lavigne, both arrived at a recent event in Las Vegas wearing black from head to toe. The Hilton hotel chain heiress arrived in a simple, short black shift dress, which showed off her back, and the tattoo on her ankle. Nicky has been busy designing her own clothing collections, with the latest, Nicky Hilton Beverly Hills, set to be showcased in Las Vegas soon. This 22 year-old launched her first line in 2004, called Chick, aimed at teenagers.
