I can see how they'd be able to get away with that, although frankly I'd be wondering who these women nobody seems to know are doing at the party. But I'm pretty sure at this point it's just a culture difference between where I live and Silicon Valley.

I work in a moderately small office, and at least once a week we get semi-random visitors from other offices. At actual parties, people bring their significant others and sometimes their friends - I wouldn't really be surprised to see a new person at a party. In fact, I'd be surprised if only familiar faces were there.
