In bridal fashion, what neckline runs straight across the chest from shoulder to shoulder?

In bridal fashion, a neckline that runs straight across the chest from shoulder to shoulder is a bateau neckline.

The bateau, also called a boat neckline, follows the curve of the collarbone and sits high on the upper chest. It usually extends toward the shoulder points, creating a broad, elegant horizontal line. The style is especially associated with refined, minimalist wedding gowns.

The term became widely familiar through twentieth-century fashion, particularly designs influenced by French couture. Audrey Hepburn frequently wore boat necklines, helping make the shape recognizable internationally. In bridalwear, it is often paired with fitted bodices, long sleeves, or structured fabrics.

A bateau neckline differs from a straight strapless neckline because it remains supported at the shoulders. It also differs from a sweetheart neckline, whose center dips into a heart-like curve.
