Tampa International Airport became the first to announce dress code rules in an X (formerly Twitter) post shared on February 26.

The travel hub revealed it's banning a popular travel outfit, explaining, "We've seen enough. We've heard enough."

While airports don't have official fashion rules, many airlines have their own dress codes.

Airports aren’t exactly known as a mecca for seeing stylish jet-set outfits, but Tampa International Airport is aiming to change that with a new PSA aimed at some of its worst fashion offenders. In a new post shared on X (formerly Twitter) on Thursday, the Florida travel hub announced a new dress code rule banning a popular airport travel staple, telling travelers, “we’ve seen enough. We’ve heard enough.”

In the February 26 social media post, Tampa Airport revealed their campaign to ban pajamas from the premises—which they shared comes after a previous offensive against Crocs footwear. “After successfully banning Crocs and giving everyone the amazing opportunity to experience the world's first Crocs-free airport, it's time to take on an even larger crisis. Pajamas. At. The. Airport. In the middle of the day,” they wrote in the announcement.

Acknowledging the many travelers who turn to sleepwear to make their flights as comfortable as possible, they quipped, “We know this decision could be disruptive to someone in your life. It's time to have a difficult conversation with them. You can do this. We (and Phoebe) believe in you.” They concluded their message, “The madness stops today. The movement starts now. Help Tampa International Airport become the world's first Crocs-free AND pajama-free airport. DO YOUR PART. SAY NO TO PAJAMAS AT TPA.”

Tampa Airport didn’t reveal if or how they’ll be enforcing the new dress code, and judging by the tone of the PSA, it seems like it’s more of a suggestion than an absolute ban. While airports don’t tend to have rules about what travelers can wear, many airlines including United, American, Spirit, Southwest, Delta, and Hawaiian say their passengers must be “properly clothed” in the cabin. This usually prohibits wearing offensive and inappropriate clothing, as well as being barefoot.
