Another day, another TikTok trend. Except unlike some of the TikTok crazes we've seen (the Tortilla challenge, anyone?) this one is actually pretty good. If you weren't at high school in the 90s, you might want to know how you would have looked in your 90s yearbook. And if you were at high school in the 90s, Granddad, then this is your chance to recreate the yearbook photos you wished you'd had.
