"swimming costumes"... are you British? :)

But yes, this apprehension of nudity is something I've always found so bizarre. Why is seeing skin of our species such a big deal? At what point of our social evolution did it evolve that way (because the idea of clothing is pretty universal to humans).

The idea of clothing isn't quite universal, but nearly so. Still, we're something of an outlier in how serious our nudity taboo is. As far as I can tell most cultures are ok with women going around topless and most think that it's ok for men and women to see each other naked when bathing, though I guess Hollywood is changing that.
