I too saw the pictures of the outfit, and I have worn MUCH more revealing clothes when flying without any problesm. I wore a cocktail dress that was more recealing than what she wore. SWA says that she didn't violate any rules, and if there is a perceived issue with dress it is supposed to be handled quietly and privately, not a public castigation.
This is some stupid, inhibited, self-righteous flight attendant and abuse of (limited) power. I think She is due a lot of apologies, reparations for public humiliation, and the attendant needs to find new work, such as handing out religious leaflets in the French Quarter.
