2225 Fillmore Street (between Clay St & Sacramento St)
Expensive but very much worth it. Great Dries Van Noten selection. Sales staff is professional and friendly, no snobbery here. Great from the aspect that it just isn't ridiculously trendy. It is pricey, yes, but if you love fashion and you're willing to pay for great clothes, come here. Cielo is awesome. If nothing else, I think it is worth it to come in while you're on Fillmore shopping in other places. Just a lovely place to browse in.
