LiquidBLUE Denim Boutique, specializing in high-end jeans and accessories, will open next month in Rockville Town Square next to Toy Kingdom. It’s the second location for LiquidBLUE (the first is in Fulton, MD), which carries brands like Hudson, Citizens of Humanity, AG, Current/Elliott and True Religion. Much of the inventory is priced in the $150-to-$200 range, with styles for both sexes. “We carry mainly Californian lines because they use the best fabrics,” says owner Jo Akin, who hired a stylist from Harrods in London to run the new store. Akin isn’t the only one betting that our area has an appetite for pricey jeans: True Religion will open its own store this summer at Westfield Montgomery Mall.
