Pottery Barn and Pottery Barn Kids, which exited the White Flint Mall last winter for the Mazza Gallerie in Chevy Chase, will be moving back to Bethesda in 2015. The two stores — and possibly PBteen as well — will share a brand new home on the ground floor of The Darcy, an upscale condo building under construction on Bethesda Avenue. This would be the second PBteen store in the D.C. area; the first makes its debut next week at Tysons Corner Center in Virginia. So if your daughter has her eye on on that aqua and hot pink floral bedding set from the PBteen catalog, take a tip from Store Reporter: Check it out in person before you plunk down your $250.
