A spaghetti strap (also called noodle strap) is a very thin shoulder strap used to support[1] clothing, while providing minimal shoulder straps over otherwise bare shoulders. It is commonly used in garments such as swimwear, camisoles, crop tops, bras, sundresses, cocktail dresses, and evening gowns, so-named for its resemblance to the thin pasta strings called spaghetti.

Spaghetti straps are not welcome at Ascot Racecourse.

Halterneck is a style of women's clothing strap that runs from the front of the garment around the back of the neck, and leaves most of the back uncovered. The name comes from livestock halters.[2] The word "halter" derives from the Germanic words meaning "that by which anything is held."  Halter is in the German word Büstenhalter, the German word for bra, with Büste meaning female chest and breasts.

The halter style is used with swimsuits, to maximize sun tan exposure on the back and minimize tan lines. It is also used with dresses or shirts, to create a backless dress[4] or top. The neck strap can itself be covered by the wearer's hair, leaving the impression from behind that nothing is holding the dress or shirt up.

If a bra is worn with a halter top, it is generally either strapless or of halterneck construction itself, so as to avoid exposing the back straps of a typical bra.

A halter top is a type of sleeveless shirt similar to a tank top (by the American English definition) but with the straps being tied behind the neck. In another style of the halter top, there is only a narrow strap behind the neck and a narrow strap behind the middle of the back, so that it is mostly backless. This design resembles many bikini tops, although it covers the chest more and may cover some or all of the abdomen at the front.
