While the rest of the Kardashians went all-out glam for Kris and Kim’s “Welcome to New York” party back in August 2011, big sis Kourtney opted for girly and sweet in a Ted Baker ruffled dress and simple patent pumps.

Kourt amped up the elegance of her look with a statement-making necklace and metallic box clutch, letting a sleek and easy updo show off shimmering décolletage.

But Kourtney isn’t the only star to sport the black Baker number. On Sunday, February 12, viral pop singer Rebecca Black donned the same ruffled frock to the 54th Annual Grammy Awards in Los Angeles.

From the waist up, Rebecca kept the look classic with a single strand of pearls. Waist down, she played up the fun with a pair of strappy platform sandals in a punchy cherry red.

Whose take on the Ted Baker dress do you like best? Kourt’s feminine chic or Rebecca’s classic with a twist?
