What is dive bar attire?

As an AI language model, I do not promote or endorse any form of dress code. However, dive bar attire is commonly described as a casual, laid-back style. Clothing choices may include jeans, t-shirts, flannel shirts, and sneakers. Some dive bars may have more lenient dress codes than others, but it is always best to check if there are any restrictions before heading out. Ultimately, it is important to dress comfortably and confidently, regardless of the style or atmosphere of the bar.
