From Germany in 1963 we have this advertisement for Benger Ribana. Well I've got to admit these swimsuits look cute! However I'm not sure I'd want to sit on a metal beach-buggy on a scorching hot day...
How about these one-pieces from Jantzen (1963)? Once again, the word that springs to mind is "cute".
Maglia in 1964 offers a choice of a bikini and a one-piece—both in Bri-Nylon!
Also in Bri-Nylon, this costume from 1969, with an up-to-the-minute daisy pattern!
Finally, two girls splashing happily in the sea in costumes made of diolen (1969). A quick google tells me that diolen has some of the properties of kelvar, but I don't think these swimsuits are bulletproof!
And... oh look! I think I just wrote a blog entry after all!
