Halterneck is a style of women's clothing with a single strap around the back of the neck. This can refer to either a dress or a separate shirt, called a halter top. The latter is a type of sleeveless shirt similar to a tank top (by the American English definition). The term "halter" comes from the German word for "holder", as in Büstenhalter, which literally means "busts-holder" and is equivalent to "brassiere".

If a bra is worn with a haltertop, it is generally strapless, as to avoid exposing the back straps of a typical bra. Some garments with halternecks may tie at the back of the neck, as is often seen in bathing suits.

In another model 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.

Halterneck garments are generally considered more provocative because they leave the upper or upper and middle back free, exposing the shoulder blades. As such, some institutions that otherwise permit casual attire (such as many American high schools) prohibit the wearing of these garments (along with spaghetti-strapped and other revealing clothing).

The halterneck dress is a classic style that can be updated in design to keep up with trends while still maintaining the overall halterneck look. It's safe to say Marilyn Monroe's figure flattering white halterneck dress in The Seven Year Itch displays how glamorous this style can be.

Each year at celebrity awards and parties there are always ladies dawning this flattering dress on the red carpet. Some were short mini styles whilst other opt for long maxi designs.

Gwyneth Paltrow was pictured wearing a striking black halter neck dress with a cut out design at a film premiere in New York and she looked every inch the susperstar.

As well as glam events like those above the halter neck dress can also be a great casual summer dress. It's an excellent light travel companion that doesn't take up much room. It can be worn as day wear and to cover up your swimwear as well as dressing it up for a romantic evening in the sun. It's a perfect sophisticated cut for all occasions.

As mentioned this style of dress is very versatile and can adapt beautifully to new trends and with other styles, like backless designs and maxi styles. The empire waistline styles are great if you want to elongate your frame especially when it is coupled with a full feminine flared style.

The variations of halter dresses are endless, some have deep plunging v necks whilst others have a sweetheart neckline and others square designs and then there are silk styles to satin.
