N-dubz's Tulisa, new style queen of hip-hop clothing?

What do you think of the Hip-hop clothing as sported by british band N-dubz?
Do you admire Tulisa's style?

Here N-dubz are with singer Pixie Lott and Tinchy Stryder, what do you think of Tulisa's style compared to fashion icon Pixie Lott?

Here Tulisa is pictured going to the Brits party in a £25 Matalan dress, is she taking highstreet celebrity fashions to a new level? Will she ever wear a designer gown?
In a way, personally I quite admire Tulisa, as she wears exactly what she wants and stands out from the crowd.
What do you think? we'll she ever be classified as a style icon? will bands like N-dubz make 'hip-hop' fashion the new thing to wear?
