A sweater vest, also known as a sleeveless sweater and tank top (UK), is an item of knitwear that is similar to a sweater, but without sleeves. They were popular in the 20th century, particularly in the 1970s in the UK, and are again growing in popularity in this century.

The name "tank top", recorded in English since 1968, derives from its resemblance to a tank suit, a style of one-piece women's swimsuit with shoulder straps, so called since the 1920s, because it was worn in a "swimming tank", an obsolete term for a swimming pool. In American English, a tank top refers to a sleeveless shirt.

One of the most common patterns on a sleeveless sweater is argyle. Many newer designs feature a return to popular patterns from eras past. Other variations include designs of a more modern nature, including stripes. Some of the most common of neckline shapes are the V-neck and the crew neck, which is similar to a common T-shirt neckline.

Sleeveless sweaters are popular among sports fans, especially those who play golf. Those with sports team logos, especially NFL and college teams, are also popular and are frequently seen being worn by American football coaches, most notably Jim Tressel who has been given the nickname "The Sweater Vest" by many American football fans despite the garment's origins at rival Michigan.

Lace was a Canadian country music group who formed in 1998 with the backing of music producer David Foster. Active between 1998 and 2001, the band charted four singles on national country music charts, in addition to releasing a self-titled studio album on 143 Records (in association with Warner Bros. Records Nashville).

Foster's plan to put together an all-female country trio began to take shape after seeing a music video of Beverley Mahood on CMT Canada while he was visiting his mother in Victoria, British Columbia; he requested to meet with Mahood, and soon after signed her to a recording contract on his label, 143 Records. Mahood later suggested her friend Giselle, a fellow singer-songwriter in Ontario, prior to David Foster introducing them to the group's third member, Austin, Texas native Corbi Dyann. The trio received a Juno Award nomination in 2000 for Best Country Group or Duo. They also received nominations for Group of the Year and Video of the Year ("I Want a Man") at the 2000 Canadian Country Music Awards.
