Boat neck/bateau necklines run straight across from shoulder to shoulder, sitting just below the collarbone. They are popular in vintage and nautical-inspired looks and help emphasize the neck while widening the appearance of the shoulders

Collared necklines are most commonly found on button-down shirts or formal blouses, but dresses and other blouses may also employ them to add a tailored and polished finish. Collars come in various styles like rounded, banded, and Peter Pan.

Cowl necklines feature loosely draped fabric around the neck or collarbone that creates gentle folds. This type of neckline is often found on soft knits, jerseys, and dresses or blouses made of satin. It can be flattering on various bust sizes and body types.

Halter tops feature straps or a tie that closes behind the neck, leaving the shoulders and upper back bare. This type of neckline is great for accentuating the shoulders and upper body. While most commonly found in swimsuits, it is also featured in dresses and evening wear.

Turtlenecks feature a “tube” of fabric that covers the neck and folds over itself for extra warmth. In terms of common high neckline shirt types, sweaters and long-sleeve shirts are common. Mock turtlenecks or mock necks, for short, have a slightly shorter fitted collar that doesn’t fold, and sometimes feature zippered styling.

An off-the-shoulder neckline rests below the shoulders, leaving them bare. Often, it includes elastic or fabric bands to provide tension to keep the garment in place. It’s best worn with strapless or stick-on bras and is popular in summer styles and evening looks.  

One shoulder necklines have a strap or sleeve on one side, with the other side being exposed at the shoulder. This type of neckline can be either curved or straight, and it’s common in both formalwear and jumpsuits.

Scoop necklines have a shallow, wide curve. U-shaped necklines are similar but have a deeper and longer curve toward the bust. Both types of related necklines emphasize the collarbone and decolletage and can be flattering on a variety of body types.

Square necklines have straight horizontal and vertical lines that enhance structure and balance, especially on curvier figures. This type of neckline also enhances the neck and collarbone areas. You’ll often see square necklines paired with wide straps or puff sleeves, and in vintage-inspired designs.

This type of neckline dips into a “V” shape in the front, but the angle of the “V” can be either shallow or plunging. Helping to elongate the neck and flatter the bust, V necklines are versatile and great for pairing with necklaces.  

A strapless neckline sits above the bust but under the arms, exposing the shoulders, collarbone, and upper chest. Similar to an off-the-shoulder neckline, this type of neckline often includes elastic for support, and is often featured in formalwear as well as bridal gowns or summer tops.

Convertible necklines have straps that you can reconfigure or remove, transforming it into a halter top, criss-cross shape, or one-shoulder configuration. This type of neckline is, therefore, extremely versatile and great for travel, giving you multiple different looks in one piece of clothing.

Illusion necklines have transparent or semi-transparent fabric at the neckline, creating the illusion of a strapless style with extra coverage. Often, the transparent or semi-transparent fabric is embellished with lace, beads, embroidery, or other decorative elements. This type of neckline adds a touch of whimsy and elegance while maintaining modesty.

Scalloped necklines have soft, rounded “scallop” shapes along the edge of the neckline, often complementing other base shapes like V-neck, scoop, or square. These scallops add a delicate, feminine element to the garment as well as texture and visual interest.
