Definition & Meaning of "trench coat"

What is a "trench coat"?

A trench coat is a classic and timeless wardrobe item that is typically made of waterproof or water-resistant fabric such as gabardine or cotton, and is designed to provide protection from rain and other wet weather conditions. The coat is characterized by its long length, typically falling below the knee, and features a double-breasted front with buttons, a belt that cinches at the waist, and wide lapels that can be turned up to provide additional protection from the rain. Trench coats may also feature a storm flap, shoulder epaulets, and adjustable cuffs. Originally designed as a military garment, the trench coat became a fashionable and practical item of clothing for men and women in the early 20th century, and remains a popular choice for a classic and stylish outerwear option today.
