I agree she def had an influence but who wouldnt with your choice of all designer clothes? She was given so much to work with.
Who cares that she's starting a line of clothing? Her so-called style on Sex and the City had nothing to do with her..she was styled to perfection by Pat Field. She is just another celeb licensing her name to make more $$$.
Many wouldn't have an influence. Designer goods don't buy taste.
