They say age is but a number. Which is why you tally birthdays like The Count from Sesame Street. (One more! Wa ha ha ha.) But at new boutique Vintage a la Mode, older is better — and fine lines are nothing steam can’t fix. Duck into the Laurel Heights Victorian parlor for a tightly edited collection of designer fashions, shoes, handbags, jewelry, and hats from nearly every era. The assortment includes never-worn collectibles in mint condition. Ungaro gowns, Valentino suits, and stone marten stoles are a stylist’s dream come true, as are coats from the ’50s and ’70s by local icons I. Magnin and City of Paris. Owner Springer Teich amassed it all and, not surprisingly, her personal ensembles are to die for. You might say she’s one smart Cookie. Vintage a la Mode, 3234 Sacramento Street, between Lyon Street and Presidio Avenue (415-440-1554).
