Hosiery, also referred to as legwear, describes garments worn directly on the feet and legs. The term originated as the collective term for products of which a maker or seller is termed a hosier; and those products are also known generically as hose. The term is also used for all types of knitted fabric, and its thickness and weight is defined in terms of denier or opacity. Lower denier measurements of 5 to 15 describe a hose which may be sheer in appearance, whereas styles of 40 and above are dense, with little to no light able to come through on 100 denier items.

The first references to hosiery can be found in works of Hesiod, where Romans are said to have used leather or cloth in forms of strips to cover their lower body parts. Even the Egyptians are speculated to have used hosiery as socks have been found in certain tombs.

Most hosiery garments are made by knitting methods. Modern hosiery is usually tight-fitting by virtue of stretchy fabrics and meshes. Older forms include binding to achieve a tight fit. Due to its close fit, most hosiery can be worn as an undergarment, but it is more commonly worn as a combined under/outer garment.

William Pierre Robert (born August 1, 1955) is a radio disc jockey who, since 1981, has been a highly popular on-air personality for 93.3FM WMMR in Philadelphia, one of the nation's most recognized rock music stations.

He is known as WMMR's most identifiable personality, and is often described as a hippie by many locals. Robert is also famous for addressing his listeners as "citizens", as well as saying "Great day in the morning!".

Robert also holds significant stature in the American rock music industry, where he is held in high esteem by many rock musicians and groups, many of whom have granted Robert rare interviews and appeared in person on his program.

Pierre Robert (pronounced "row-BEAR") began his radio career at 94.9 KSAN-FM, one of the country's first progressive rock stations, in his hometown of San Francisco. When KSAN changed its format to an Urban Country & Western style in the early 1980s Robert assumed the on-air name "Will Robertson" for a brief period of time.

Not long after, Robert moved to Philadelphia where he joined WMMR.
