A kosovorotka (Russian: косоворотка) is a Russian, skewed-collared shirt. The word is derived from koso - askew, and vorot collar.

A kosovorotka is a traditional Russian shirt, long sleeved and reaching down to the mid-thigh. The shirt is not buttoned all the way down to the hem, but has several buttons at the collar (unfastened when the garment is pulled over the wearer's head), though these are positioned off to one side (regional styles vary between left and right), instead of centrally, as is customary with a typical Western 20th and 21st century man's shirt. If left unbuttoned the collar appears skewed, which accounts for the garment's name. The collar and sleeves of kosovorotka were often decorated with a traditional Slavic ornament.

Today kosovorotka are perceived mostly as men's shirts. However, the shirts for women and children are not too much different from the men's variant, and the word kosovorotka in fact is often used to denote just any kind of shirt. The men's garment was worn loose and was not tucked into the trousers, but instead belted either with a conventional belt, a rope, or a rope-like tie. The tails of the garment hung over the trousers. Women's shirts were tucked into the skirt or worn under the sarafan, and indeed tended to have a straighter collar. Children's shirts were often too long for those who wore them, and was the only piece of clothing on little boys and girls in the ancient times.

Evgeni Viktorovich Plushenko (Russian:  Евге́ний Ви́кторович Плю́щенко​ (help·info), Yevgeny Viktorovich Plyushchenko; born November 3, 1982) is a Russian figure skater. He is the 2006 Winter Olympics gold medalist, 2002 Winter Olympics silver medalist, and 2010 Winter Olympics silver medalist, three-time (2001, 2003, 2004) World champion, seven-time (2000, 2001, 2003, 2005, 2006, 2010, 2012) European champion, a four-time Grand Prix Final champion and a nine-time (1999–2002, 2004–2006, 2010, 2012) Russian national champion.

Plushenko was born in Solnechny, Khabarovsk Krai, Soviet Union. Since he frequently suffered from colds, his mother decided he needed exercise and enrolled him in figure skating lessons at age four. When he was eleven years old, Plushenko's ice rink in Volgograd closed. He was then sent to Saint Petersburg to train under the tutelage of Alexei Mishin.

Plushenko made quick progress on the international scene under Mishin's tutelage. As a 14-year-old, he won the 1997 World Junior Championships. The following year, at 15, he finished third at the senior 1998 World Championships.
