Welcome to the decade defined by fake tans and frosted lipstick.
The infamous rule of "only one fedora per crew" should probably be switched to "zero fedoras per group," because this hat looks silly no matter who you are or what hairstyle you have.

In the late '90s and early '00s, celebrities began getting arm bands with spiky, pseudo-tribal designs. We're still not sure why.
