Forever 21

Forever 21 reemerged from bankruptcy with the identical disposable fashion model, despite having been sued for copyright infringement over 50 times—outpacing Fashion Nova (#7) by 30% more lawsuits. The brand's post-bankruptcy revival by Authentic Brands Group failed to cut its 12% annual growth in unsold inventory, meaning 1 in 5 items ends up in landfills within a year, a concrete measure of its lasting harm over newer rivals.
