Those strike me as models, not party attendees, presumably paid to pose for that photo, or to be at some event in which the photo was taken. They are not dressed in black tie attire; they are dressed in a sexy, posed, clearly pre-coordinated "booth babe" take on black tie. I could be wrong, but that's the impression the photo gives me.

Techweek specifically said they were attendees posing in a photo booth. You might question that, but would it make a difference?

So is the issue that there's no guys in the picture or that the women are too beautiful?

[domdip]

Neither. You can add a leering guy to the picture and it will still be offensive. There are probably pictures with beautiful women that would not be offensive.

The 'issue' has been described several times in the comments and in the original article. Trying to reduce it to one feature isn't helpful.

[kristofferR]

The original article says nothing at all about what the problem is and the comments here says a lot of different things, most doesn't make any sense at all (complaining about sexualizing a rave...).
