Workwear bib and braces are a type of workwear clothing that includes a bib-like garment attached to straps that go over the shoulders, and sometimes include a waistband to hold up pants. They are typically made from durable materials like denim, canvas, or polyester, and are designed to provide protection and comfort for workers in a variety of industries. 

Bib and braces are often used in jobs that involve manual labor or working in harsh environments, as they offer additional coverage and protection to the wearer's upper body. They are commonly worn by carpenters, mechanics, welders, farmers, and construction workers, among others. 

Modern bib and braces often feature multiple pockets for storing tools or personal items, and can be adjustable to fit a range of body types. They come in a variety of colors and styles, from traditional denim to brightly colored options for high-visibility purposes.
