'Avatar' actress Zoe Saldana says she believes fashion is an 'art form' and so she puts a lot of effort into picking out her outfits.

The actress, who once launched a clothing line with her sisters and has a fashion database website myfdb.com with her fiance Keith Britton, loves taking time to put an outfit together as she knows it's important to get the right look, reports contactmusic.com.

'Five years ago my sisters and I created our own brand, called Arasmaci, but we actually produced no more than a few T-shirts and some accessories because I became overwhelmed by 'Avatar',' she said.

'For many people, including a lot of actresses, fashion is all about brand names, logos, status symbols, but for me, it's an art form,' she added.

Saldana also said that part of her job is to look good but she would never wear anything that made her look 'cheap'.

'My body is my office, you might say. Half the job of someone in showbusiness is creating an attractive image. And for me, that doesn't mean becoming a cheap sex symbol,' she said.
