The N-Dubz star and X Factor judge told Capital FM that she just wears what she likes.
"I have a stylist that has to understand what I like to wear and get the stuff that I want," she said.
"It's complicated, for me I'm not so much into fashion, or labels, or seasons or what's in, I don't care."
She added: "I just wanna wear what I like, so if I say to her, I like being glamorous but I wanna be urban so you have to make that work for me.
"So she'll then maybe bring in a pattern that is this season which I wouldn't know anything about, but make it urban."
