“Ashley remembered my birthday, but I don’t hold grudges against Mary-Kate for forgetting mine,” Lizzie said politely. “She was out of town. I should have just said my brother (laughs). We’re all very close.” Happy belated birthday!

FYI: Elizabeth is wearing a Maison Martin Margiela top and skirt, Bionda Castana shoes, and a Marni necklace.
