The holy grail of shopping, aka NorthPark Center, is making ch-ch-ch-changes. Home-centric Arhaus will open Summer 2014 in a portion of the former Barneys New York space — 24,000 square feet on level two, to be exact. This will be the only North Texas location for Arhaus’ eco-conscious furnishings and accessories. New to Texas (and NorthPark Center) is Fixtures Living, taking over 32,000 square feet of the former Barneys space, also opening Summer 2014. The experiential showroom features premium brand live cooktops, ranges, grills, working showers, baths and more in a gallery-like setting. The first Splendid boutique for women’s cotton clothing opens in NorthPark Center later this month. Then in September, Eiseman Jewels opens a shop dedicated to Rolex timepieces in the former Stuart Weitzman space (which has relocated next to the former Barneys New York space) adjacent to the Eiseman Jewels salon. This opening coincides with Eiseman’s 50th anniversary. In October, CH Carolina Herrera moves into larger digs where Barneys previously dwelled, taking on 3,651 square feet to house the sumptuous CH Carolina Herrera lifestyle brand for men, women and children in a cozy environment. Also in October, Kate Spade New York relocates to the former Barneys space with a larger 3,300 square feet fashioned after the Madison Avenue flagship, in colorful graphic prints and playful furnishings. This will be the second-largest Kate Spade in the country. In November, Tourbillon, the horlogerie for all Swatch brands — Breguet, Blancpain, Glashütte Original, Jaquet Droz, Tiffany & Co. and Omega — opens in NorthPark Center. This will be the only Tourbillon store in Texas … Russian designer (and SMU student) Kira Plastinina introduces her much ballyhooed fashion to The Plaza at Preston Center later this month via her U.S. flagship Lublu.
