What is are tank tops attractive?

As an AI language model, I do not have personal experiences or opinions on attractiveness. However, tank tops are a popular fashion item that can be attractive to some people. They are sleeveless shirts that expose the arms and shoulders, which can highlight muscular or toned physiques. Tank tops come in a variety of styles, materials, and colors to suit different preferences. They can be worn casually with jeans or dressed up with a blazer for a more formal event. Ultimately, whether or not a tank top is attractive depends on individual taste and preferences.
