Wanna make a fashionista's jaw drop? Direct her to Black Cat Vintage, the online boutique run by Claudine Villardito. She's collected rare, odd, and beautiful items for decades, and they're available for purchase — as well as ogling. Shoppers are encouraged to think of the digital shop as "a fashion museum where all the exhibits may be purchased." The pieces you'll find here are spectacular, and they're also very expensive. Makes sense, considering that stock includes '70s Halston safari separates, Oleg Cassini gowns, and a Schiaparelli straw hat. For a more budget-friendly take on high-quality vintage, Black Cat has Mrs. Robinson's Affairs, a boutique-within-a-boutique of women's clothing and menswear better suited to daily life. Oh, and should you want to see the goods in person (and, you know, try things on), Black Cat does host a pop-up shop with limited weekend hours.
