N-Dubz's Tulisa Contostavios is the subject of a sophisticated makeover in this month's issue of Look magazine.

The frontwoman ditches her bling for a black sequinned dress in one shot, and wears a pussy bow shirt in another.

N-Dubz have set their sights on breaking the lucrative U.S. market, and Dappy has recently mentioned that the band are updating their image in order to do so. He said:

"Fazer and I have been inspired to wear more tailored suits and smart jackets. You have to evolve."

Contostavios' shoot was done to celebrate Look magazine having its own show on February 18 as part of this month's fashion week.
