Sweetheart neckline

Also called: sweetheart

A sweetheart neckline is an edge with two curves over the bust that meet in the middle, like the top of a heart.

How to recognise it

Two rounded curves over the bust with a dip in the middle. Usually on strapless or thin-strapped garments with a boned bodice.

Where it comes from

The neckline was fashionable in Victorian evening dresses, and in the 1940s and 1950s Hollywood stars and bridal designers made it popular.

Who and when it suits

Romantic and feminine, it is common on evening, cocktail and wedding dresses and corset tops. It accents the bust and neck.

Variations and look-alikes

It comes strapless, on thin straps, with a sheer illusion panel up to the neck or with sleeves. A gentler, slightly curved version is a demi-sweetheart. It differs from a straight strapless edge in its two curves.

How to style it

  • You will need a strapless bra.
  • A short necklace or statement earrings.
  • Hair up shows the shoulders.
  • The bodice must hold firmly.
