I am looking for shops in San Francisco that carry US sizes 14-16 (women's). As it is a vacation, I would love to visit locally owned boutiques with unique pieces and good service. But it seems many of the local boutiques stop at a size large. If the Nordstrom's/Macy's ect... women's section is particularly good I would also like to know.
I am interested in all kinds of clothing (cocktail dresses to casual, although I have plenty of denim) and all price points excluding new expensive designer. By that I mean that I might be willing to spend $200-300 on a special dress but that cheaper is also great. I don't want anything too on the edge of fashion but I don't want blah, although good quality basics are also appreciated. I am open to discount designer stores and vintage/consignment.
I am staying downtown (Union Square/Nob Hill) and I will not have a car, so keep all recommendations confined to San Francisco proper. It needs to be someplace I can reach via public transportation or 15-20 max minute cab ride.
Thanks for all your help!
