"Savile Row, London, 1920s. That is what came to mind when we visited this impeccable atelier in San Francisco’s historic Jackson Square. Owner and designer Lan Jaenicke will fit you for a custom piece, be it one of her architectural dresses or a silk blouse that feels like you’re cloaked in a cloud. Jaenicke, who has an unparalleled skill for creating clothing that is poetic and timeless, wanted the space to show the entire design process, from the fitting to the construction. (She actually sews some of the pieces on the premises.) You can also eye the ready-to-wear collection, all in silk, cashmere, and linen. And even if you’re not looking to shop and you’re just wandering down Jackson Street to admire the old facades, this boutique is worth a visit. Jaenicke has considered—and honored—every element of this 1860s brick-and-cast-iron building that was once the original Ghirardelli chocolate factory. She punctuated the space with antique scales, shimmering selenite hearts, and dried lavender. Everything is in harmony here."
