I think Frankie is one of the better known out of the group, she's pretty much the founder I think (could be wrong) - I also quite like her style, it's pretty distinctive, anyway. Mollie I think is photographed a lot for her blond bombshell looks. I think Rochelle is the prettiest though.
It's interesting to see their style now they're becoming better known. It's not amazing, but I think they all look good.
