Sample Descriptions of the word Jacket
From Wikipedia:
“A jacket is a type of sleeved hip- or waist-length garment for the upper body. For clothing older than the mid-nineteenth century, a distinction is often maintained with a coat, but in many instances the terms are now interchangeable. A jacket is generally shorter, ending just below the waist, and often lighter. Some jackets are fashionable, while others serve as protective clothing”.
