POP-UP PARTY: Accessories e-tailer BaubleBar has turned two, and plans to turn its birthday into a birth month. The company will launch its first brick-and-mortar retail experience — a 1,000-square-foot pop-up shop called BaubleBar Unwrapped — at 344 West 14th Street in Manhattan’s Meatpacking District from Feb. 1 to 16. (The 16 is a nod to how the e-tailer got its beginnings: cofounders Amy Jain and Daniella Yacobovsky share the same birthday, on Aug. 16.) The shop will offer an array of the e-tailer’s signature pieces — such as its best-selling bangle bar — with prices ranging from $15 to $250, and every shopper will leave with a free gift.
