Airline sorry for 'telling woman to cover outfit'

I've seen much worse outfits on airplanes. I can't even figure out what the airline crew was objecting to on this one...

I doubt that racism had anything to do with this. Looks like abject stupidity more than anything else. And maybe the fear that someone on board from the Middle East would complain. Better to solve a small problem before the flight than have a significant event after taking off. Or perhaps we should return to the 60's and just wear business clothing when flying.
