A tube top is a shirt with no sleeves or shoulders, and is, basically, a tube that wraps around a woman's torso. In Great Britain and Australia, it is called a "boob tube" (not to be confused with the identical American slang for television set).
• T-back shirt
A T-back shirt is a tank top that is much narrower in the back than the front. The style for women varies greatly from those worn by men (primarily weightlifters). Female T-back shirts cover more of the back, are less narrow, and come together higher up the back, in general. Male shirts are designed to expose the shoulder blades, useful for men at the gym.
