Avoid if

You would rather not adjust a strapless bodice through the evening

Often strapless, but also comes with straps, sleeves or a sheer illusion panel above it.

A sweetheart neckline is a bodice edge cut in two rounded scoops, one over each side of the bust, that meet in a dip at the center. The outline traces the upper half of a heart. Among dress necklines, you will see it most on prom and homecoming dresses and on formal gowns for black tie weddings.

How to spot a sweetheart neckline

Look at the top edge of the bodice. On a hanger it shows two curved arcs with a notch or soft V between them. A semi-sweetheart keeps the same shape but sits higher, with a shallower center dip. Straps, sleeves or a sheer illusion panel may sit above the curve, and the dress still counts as a sweetheart because the name describes that edge.

Two terms get mixed up with it:

Queen Anne: a Queen Anne neckline can share the same curved front, but it rises high around the back and sides of the neck like a collar, while a sweetheart leaves the neck open.
Strapless: strapless describes how the bodice stays up, with no straps at all, and it can be cut straight across. A sweetheart describes the shape, so one dress can be both.

Wearing a sweetheart neckline well

The curves frame your face and collarbones and lead the eye to the bust line. A full skirt answers that shape below, which is why a ball gown or an A-line works so well with it. A mermaid carries the fitted line on down to the knee instead. Try satin first: its body holds the curve crisply. Tulle adds softness in the skirt.

If the bodice is strapless, the fit at its top edge matters more than anywhere else. Boning and a grip strip stop it from slipping. If you would rather not adjust it all evening, choose a version with spaghetti straps.

For prom, try a floor-length satin A-line with a strapless sweetheart bodice. Add an updo and a slim pendant, and wear shoes you can dance in for hours.

FAQ

Is a sweetheart neckline formal?

It suits black tie, black tie optional, formal and cocktail attire. The length and fabric set the level: floor-length satin reads black tie, and a knee-length version fits a cocktail party or homecoming.

Can I wear a sweetheart neckline to a place of worship?

On its own, it leaves the shoulders and upper chest bare. If the ceremony expects more coverage, add an illusion overlay or a wrap, or choose a style with sleeves.

What is the difference between a sweetheart and a semi-sweetheart?

A semi-sweetheart sits higher on the chest and dips less at the center. It keeps the heart outline with more coverage. You can compare both with other shapes in the necklines glossary.
