Kontusz

kontusze; Ukrainian: кунтуш, romanized: kuntush; Lithuanian: kontušas; originally from Hungarian: köntös, lit.

In the 17th century, worn over an inner garment (żupan), the kontusz became a notable element of male Polish national and Zaporozhian Cossack attire.

Tradition states that the first kontusze were worn by szlachta who captured them from Ottomans to display as loot, which itself possibly originated from Mongol Haiqing which had openings in armpit.

[citation needed] Throwing kontusz sleeves on one's back and stroking one's moustache was considered to be a signal of readiness for a fight.

In Poland, the kontusz was worn mainly by the nobility, but it was also adopted by the Zaporozhian cossacks when Ukraine and Ruthenia were under Polish rule.
