Slash neckline

A neckline cut with a vertical or diagonal slit at center front—the slash opening on evening gowns and blouses, sharper than a soft V and often deeper than everyday necklines.

How to recognize it

Slash neckline shows a deliberate slit cut at center front throat or chest.

Plunging is a deep décolletage family. V-neckline is an open V without a slit edge.
