Loose sock
Loose socks (Japanese: ルーズソックス, rūzu sokkusu) are a type of sock that is popular among young Japanese girls.
They are nearly always white and are very long, in some cases up to almost 2 meters. They are usually worn below the knee, held up with an adhesive called sock glue and sock touch, and somewhat resemble leg warmers.
Some girls in lower secondary school (junior high school) and upper secondary school (senior high school) wear loose socks with their school uniforms. Certain schools forbid pupils to wear loose socks at school, so girls from these schools will often change into loose socks and wear them outside the school campus. The trend has also spread to some primary-school pupils.
In Japan, loose socks have been in fashion since the mid 1990s but since 2002 have become far less popular.
