A sleeveless sweater (known as a tank top in the United Kingdom, a sweater vest in North America and a Langdon in the Northeastern United States) is an item of knitwear that is similar to a sweater, but without sleeves. They have been popular in the 20th century, particularly in the 1970s in the UK.
The Sweater Vest should never be worn....IT SHOULD BE ROCKED!!!
