Kilt

A kilt is a garment worn by men of the Scottish Highlands, which first originated in the 16th century.

In the EMPATH: The Luckiest Smurf story series, Duncan McSmurf is the only Smurf in Empath's generation of Smurfs who actively wears a kilt. Unlike his father Angus McSmurf, Duncan wears his kilt over regular white Smurf pants in his normal everyday activities. During more leisurely activities in the summer, Duncan may just wear the kilt by itself along with a pair of shoes or sandals.

Kilts were also worn by the other male Smurfs during their time-traveling adventures in The Lost Year.
