The design world went into a collective mourning late last year when Rosselli announced the closing of his eponymous Upper East Side store—long a favorite source for top designers and in-the-know shoppers. But fans of the talented antique dealer were dealt some good news when Rosselli announced that he'd be auctioning off much of his inventory through Stair. Rosselli—much like Buatta—is a prolific and exuberant collector, a habit that has fueled his several shops, given character to his own homes (most of which he shares with his wife, the celebrated designer Bunny Williams, with whom he also ran the beloved store Treillage), and made him a go-to resource for many of history's top designers.
