3
For Serena: Wear an oversized white button-down shirt untucked or half-tucked into a low-rise grey pleated skirt. Loosely drape a black necktie around the open collar.

Makeup & hair

Blair requires a polished, glossy brunette blowout or neat curls with perfectly manicured makeup. Serena needs messy, textured blonde waves with a natural, sun-kissed makeup look and minimal effort.
