Soviet Navy’s Pacific Fleet sailor in full dress.
The telnyashka (Russian: тельня́шка) is a white undershirt horizontally striped in various colors, and dates back to the 19th century Tsarist Navy.
It is an iconic uniform garment worn by the Russian Navy and the Russian Naval Infantry (marines).
The telnyashkas originated with distinctive striped blouses worn by the merchants and fishermen of Brittany.
The fashion was later adopted and popularized by the French Navy and other navies of the pre-Dreadnought era.
Telnyashka has become such evident symbol of masculinity in Soviet culture, that it is sported by dozens of popular non-military characters of the cinema and even children’ cartoons. There is a popular saying that describes the wearing of telnyashkas as an indicator of a “real man”; "We are few in number, but we wear telnyashkas!"
