Sandy Olsson
Looking for a low-maintenance costume consisting of pieces you already own? Go for “bad girl” Sandy from Grease. We love Gigi Hadid’s take on the character, from the black ‘fit to the red nails and lip—and, of course, the star of the show, the curly, voluminous hair. Feel free to embrace your natural texture or use a small curling iron; just remember to not run your fingers through your hair after.
