unitard

This term is a portmanteau of "unit" and "leotard," specifically distinguishing the garment by the inclusion of full-length legs. While a leotard ends at the hip or thigh, a unitard provides full coverage down to the ankles, making it a staple in high-performance athletics and contemporary dance where modesty or muscle warmth is required.

In a professional context, the word carries a connotation of athleticism and precision. It is rarely used in casual fashion contexts unless referring to specific athletic gear or costume design, as the garment's primary purpose is to minimize wind resistance and maximize range of motion without fabric interference.
