Necklines do more work than you think. The shape framing your face and décolletage can completely transform a dress–making it feel office-ready, date-night perfect, formal, or effortlessly off-duty. And yet, most of us are still defaulting to the same two or three styles without realizing just how many options are out there. Whether you’re deep in a scroll session or standing in a fitting room, knowing your necklines is the kind of low-key style knowledge that pays off every single time. Ahead, all the different types of necklines you’ll encounter while shopping for women’s dresses—and exactly what to know about each one.

Apron
