For their outing, the Poosh founder slipped into a thigh-skimming blue and white wrap dress, which showcased her tan and toned legs.   

Meanwhile, her lookalike bestie donned the exact structured garment, with a plunging neckline, in beige with a black leather purse on her shoulder.

Both women wore their straight brunette tresses down with a sleek center part, but tied their frocks differently and Rae rocked an eye-catching neon pink nail polish.

Despite the pals’ staggering 22-year age gap, this is only the latest public display of their high-profile friendship, which regularly includes influencing each other’s style.
