To dress up as these family-favorite sisters, we suggest plenty of scrunchies and a teasing comb. Full House was the epitome of late ’80s-early ’90s fashion, so start digging through your old clothes or visit the thrift store for bright colors, denim, and big sweaters.

Before there was Full House, there was The Brady Bunch, which came with plenty of sister-induced drama. Whoever dresses as Cindy will have to rock pigtails (braided or curled), Jan will need an eternal chip on her shoulder, and Marcia will need board straight hair with a center part. Bonus points if you find a big enough crew to play the entire family.
