Swimwear

I've been invited to a party where the dresscode is vintage swimwear. Going to a party in just swimwear is a challenge in itself, but vintage swimwear? Male swimwear of the past has not been very inspirational.

I can't bring myself to say to the person organising it 'I'd love to go but I just don't want to go drinking in a pair of beige speedos.'

Maybe it's just a sign that I'm getting old, or at least tasteful.
