London: Tennis icon Serena Williams, who has her own clothing line, says she would have loved to be a full-time designer but she feels fashion shows need a lot of work. The 34-year-old, who has been crowned Wimbledon champion seven times, says if she was not a successful tennis player, she would have wanted to pursue a career in the fashion industry and design her own fashion range, reports femalefirst.co.uk. "I'd be a fashion designer. I've played Wimbledon, I played the Open, I'm playing tournaments in between designing. When you work on the shows it's not like it takes two weeks. "It's a four, five, sixth months' commitment. It was a lot of preparation. All of the looks -- pairing it, first, last, finale, middle... music. It was a lot,” Vogue magazine quoted Williams as saying. Williams has been running her own label Aneres, which is her first name spelled backwards, since 2004. Meanwhile, the Michigan-born professional shared that she is obsessed with footwear and would love to raid singer Mariah Carey's show wardrobe.
