Nice photos. How do you know it's 1978? To me the bathing suits seem more closer to the 1980s.

Anyway, great photos. Where did you get them? What's the story?

I was 10 in 1980 so the swim suit that the dude is wearing in the last photo looks like Birdwells which where 1970s to early 1980s.

The ladies bikinis look like an 80s cut but Rio might be the leader in the swim styles. Nice photos. Next time give a little story of is possible.
