Undershirt vs. Onesie

By Jaxson

  • Undershirt

    An undershirt is an article of underwear worn underneath a dress shirt intended to protect it from body sweat and odors. It can have short sleeves (T-shirt) or be sleeveless (A-shirt). The term most commonly refers to upper-body wear worn by males.

    An undershirt may be worn to protect the body from stiff or otherwise uncomfortable fabric. It also makes dress shirts less transparent, can be worn during winter months as an extra layer of warmth, and reduces wear on the upper layers of clothing.
