Hi Emma,
I have a pair of these jeans and I love them but am gutted that she ended her sponsorship deal with Rock & Republic. She's now producing her own range under her DVB label with a family-run Canadian firm called Western Glove Works Ltd and I just don't like them. Rock & Republic wont even let her use the embroidered crown logo that was sewn on the pockets which I thought made them unique.
However I know that you can buy her R&R range at La Canada on the upper level near Game (sorry cant remember the name of the shop).
Hope this helps.
