What are the different types of necklines for wedding dresses and prom dresses?

You may wonder what is the difference between various necklines. None of this will be part of your next school exam, however we included some definitions just in case you wanted to know.

Necklines can be grouped into categories according to their shape and where they cut across the body:

• Polo neck (circular)

these are high close-fitting collars that wrap around the neck itself, and are also called turtlenecks. They are most common for sweaters (also called jumpers) or jerseys.

• jewel neckline (circular)

these are round and sit at the base of the throat, and are also called the T-shirt neckline.

• scoop neck (curved, concave up)

these have a curved U shape, with the arms of the U hanging on the shoulders. The depth of the U can vary, ranging from demure styles to plunging.

• V-neck (2-4 linear edges, side edges diverge)

these are formed by two diagonal lines from the shoulders that meet on the chest creating a V shape. The depth of the V can vary, ranging from demure styles to plunging. The surplice version of this neckline (known as a portrait neckline) is an alternative. The V may also be truncated by a small bottom edge, forming a trapezoid shape.

• square neck (linear side edges neither converge nor diverge)

these are characterized by three linear edges, the bottom edge meeting the side edges at right angles. The bottom edge cuts across the figure horizontally and the side edges pass over the shoulders. A special case of this is the slot neckline, in which the side edges are very close (roughly the width of the collar-bone points), forming a narrow slot.

• deep or plunging neck

these are low necklines, in either V, U or square shapes, that reveal various amounts of cleavage.

• boat neck (one edge, nearly linear)

these have a high, wide, slightly curved neckline that pass past the collarbones and hang on both shoulders, and are also called bateau necklines or Sabrina necklines. A variation is the portrait neckline.

• off-the-shoulder (one edge, nearly linear)

these are similar to boat necklines but are significantly lower, below the shoulders and collar bone. Usually these pass over the arms but, in the strapless neckline style, may pass under the arms. These necklines accentuate the shoulders and neck of the wearer.

• one-shoulder necklines (one edge, nearly linear)

these are asymmetrical linear necklines that cut across the torso diagonally, usually from one shoulder to under the other arm.

• halter necklines (linear, side edges converge on neck)

these feature a V-neck or scoop front neckline with straps which wrap around and connect at the nape of the neck.

• sweetheart necklines (side edges linear, curved bottom edge concave down)

these have a curved bottom edge that is concave down and usually doubly scalloped to resemble the top half of a heart. The side edges often converge on the neck, similar to halter necklines. Sweetheart necklines accentuate the bosom.

• keyhole necklines

these are similar to halter necklines, but the converging diagonal lines meet in front of the neck, forming a "keyhole". More generally, these feature a central hole, usually just below the collar bones. These necklines are seen infrequently.

• surplice neckline

these are similar to how a bathrobe's neckline is formed by one side of the garment overlapping the other. For a dress, the lower layer is usually sewn to the top layer just under the bust.
