brown mustache

Many brown mustaches use a self-adhesive backing with a peel-off strip; listings commonly describe them simply as self-adhesive.

Sizing is typically aimed at adults: listings often use "Men's" sizing, list "one size," or state the piece fits adults or most teens and adults.

Listings reference multiple brown shades, including light brown, medium brown, and dark brown.

A mustache-and-beard color product lists a processing time of about 5 minutes and notes it "works in 5 easy minutes."

Age ranges vary: some listings are labeled "14 years and up" or "16 years and up," while others are listed for "Adult."

Brown mustaches commonly appear in Western costumes, retro looks from the 1920s–1980s, pirate outfits, celebrity/athlete/politician impersonations, and uniformed-occupation costumes.
