National LookAlike Day Cards

An informal, novelty observance celebrating people who resemble one another — twins, doppelgängers, celebrity look-alikes, and friends who coordinate appearances. There is no widely documented origin or official sponsor; the day emerged from popular culture and internet/social media practices where people share photos of matched outfits or uncanny resemblances. The significance is lighthearted: it encourages playful imitation, creativity in costuming and photos, social connection, and engagement on social platforms rather than commemorating a historical event.
