Just because she's an Upper East Side gal doesn't mean Lizzie Tisch is afraid of dropping an F bomb: "We put the F-U in fun," she says of her retail site, LTD x Lizzie Tisch. Tisch is certainly not alone in dropping a four-letter word or two this holiday season, which is why her month-long holiday pop-up at 828 Madison Avenue feels like a shot of vodka-laced espresso for weary 2020 shoppers. Tisch, a former T&C Jewelry Champion of the Year, put up her her wares at the former Cartier mansion, unrecognizable with a punk rock snarl of ceiling ducts wrapped around a black chandelier and "Don't Wreck the Holidays" spray-painted by artist Brian Kaspr on exposed brick. The refashioned boutique is stocked with covetable items that promise to make holiday shopping enjoyable, including a chill organic body wash from Onda Beauty, a luxe embroidered cashmere sweater from Leret Leret, and a chic emergency kit (really!) from Judy. And that's not to mention New York favorites like handmade glasses from Paul Arnhold, colorful Edie Parker home decor, and sets of McKenzie Liautaud masks, which promise to be this year's smartest hostess gift. "I believe so strongly in the strength and resilience of New York City, so we are pleased to help do our part by activating with this great, diverse selection of vendors,” said Tisch. The pop-up, which naturally follows all Covid-19 guidelines, is open through December 15. For those who can't make it in person, Tisch has shared a selection of her favorite items to shop online now.
