I thought it was a tad strange how Fallout 76 had so many outfits centered around showing school pride that seemed to be primarily for male characters.
From all the variations of letterman jackets, the Atomic Shop tracksuits and sports outfits, there was never really an inherently female-centered equivalent outfit (not to imply that said outfits are exclusively meant for male characters, mind you) showing off their spirit for the days of pre-war academia.

We've got Morgantown High, Grafton High, Watoga High, and Vault-Tec University all represented as fine establishments for the nurturing and growth of America's youth to prepare them for the future. All these institutions partake in the great American pastime of sports, though I haven't seen any reference to any cheerleading which may have existed alongside West Virginia's best school teams.

That said, I whipped up this cheerleading outfit with the help of a friend to remedy such a perceived non-issue. And if nothing else, you can wear this as a Halloween costume in a pinch. After all, spooky season is just around the corner~

I made a male version too because I don't believe in half-assing things!
