What is a halter?
Halter (from the English halter - a rein, a clamp) is a type of cut in which the straps or a one-piece part of the bodice are tied or fastened at the neck, leaving the shoulders and back open.

When searching for an answer to the question "what is a halter bra?", it's important to understand: it's specialized underwear with a strap over the neck, designed to support the breasts under clothing with an open back or halter neck.
Historically, this cut gained popularity in the 1930s in beachwear and evening gowns. Today, it is the standard for lingerie, everyday tops, and swimsuits.
Main types
A classic halter bra features padded cups and a single adjustable strap. It provides support and remains discreet under evening dresses.
This lace halter bra features a soft, non-wired bra that extends to the bottom. It can be worn as both underwear and as a standalone piece, like a crop top.

A high-neck halter top or swimsuit bra is a top or bra in which the fabric completely covers the chest, down to the collarbone. The design forms a stand-up collar that ties at the nape of the neck.
What to combine with
As part of lingerie styling, smooth halter bras are worn strictly under halter dresses and tops. They are also essential when wearing off-the-shoulder garments or those with a low back.

For everyday looks, pair a lace halter bralette with an unbuttoned, oversized cotton shirt. Complete the look with an oversized blazer and high-waisted, straight-leg jeans.

For evening wear, silk halter tops are paired with palazzo pants or satin midi skirts. This creates an elongated silhouette and accentuates the shoulders.
