This is vintage for the finicky. No wading through bins, no discarding racks’ worth of garments for signs of age or questionable authenticity. Co-owner and former high school history teacher Rachel Hirsch works with suppliers from around the globe, and each piece that she pulls into her immaculate Porter Square shop is carefully inspected and arranged by decade. The finishing touch is a tag describing the occasion for which some stylish woman could have originally donned the garment. Reads the legend for a black velvet babydoll from the ’60s: “This might actually be a fun New Year’s Eve.” Chances are, your night out in any History purchase will be equally memorable.
