For those who like the thickness of Sam Elliott’s mustache but want a tamed version like Ron Swanson, the walrus mustache style is the perfect sweater for your top lip. To grow this thick mustache, you’ll need to spend some time letting your hair get as long as possible. Many people confuse the walrus mustache style with the Chevron mustache or even handlebar mustache. It’s actually much more refined, stemming from historic roots in late 19th century to early 20th century.
