Boxers or boxer shorts or loose boxers are classified as an undergarment worn by men. They are popular in the boxed, checkered pattern and got popular in the 1944 to provide for unhindered leg movement for men when they wore this. Most boxers are worn by expanding the elastic at the waist, while some have a fly or buttons in the front. Boxers are now available in various colours from solid to checked and in different materials like cotton, polyester, silk etc.
Boxers for women have become common in the recent years and resemble the male boxers. They are used as loungewear rather than an undergarment.
