Vintage Overalls

I want to find and buy a swimsuit vintage style (male) you have all seen in cartoons and movies: striped black and white overalls sort of thing. Where are they purchased? And what is their technical name?

Ebay or Craigslist?

Daddy's drawers

You can buy in stores or in the city.

Hire a seamstress to custom make you a set from a model. I know there are many vintage / costume sewing patterns that have what you are looking for. A good seamstress could do in one day.
