RA: I’d heard of this Antwerp store, started last year by two graduates of that city’s Royal Academy of Fine Arts, but it wasn’t until I visited on vacation just last week that I understood how terrific their vision is. On blogs, RA is often mentioned in the same breath as other intimidatingly high-end concept shops, but despite carrying similarly priced clothes, RA feels less like a museum and more like a playground — which could be because of its kooky site-specific installations. You feel like you could don some Linda Farrow sunglasses, wrap yourself in a vintage Guy Laroche fur, and plop down on this cozy woven carpet by artist Irene Alvarez, which was inspired by Incan art and features cartoons, monsters, and weird microchip patterns.
