Why schools love 90s day
90s day has become one of the most popular spirit week themes because it is easy, affordable and fun for everyone. Students can usually build an outfit from their own closets or a parent's, teachers can join in without much effort, and the bright colors make for great photos. It is also a theme that parents enjoy, since many of them grew up in the decade.
Borrowing from parents
The best source of authentic 90s clothes is often a parent's closet or a family attic. Flannel shirts, denim jackets, band tees, overalls and windbreakers from the 90s are surprisingly common. Asking a parent what they wore in school can also lead to fun conversations and family photos.
Staying comfortable all day
Unlike a costume party, a school day lasts for hours, so comfort matters. Choose pieces you can sit, run and climb stairs in. Overalls, tracksuits, flannels and jeans are comfortable all day, while tall platforms and stiff costumes are not. Bring a jacket if you are wearing anything cropped or thin.
Group outfits for friends
Friends can coordinate for extra fun: matching tracksuits in different colors, a group of grunge rockers, or each person representing a different 90s style. Group photos at the end of the day become great keepsakes.
