Catch 22 costume designer Jenny Eagan managed to track down genuine World War II uniforms in America after first trying her luck overseas.The new mini-series, based on Joseph Heller's classic novel about Captain John Yossarian and the fictional 256th Squadron of the U.S.

Army Air Forces, premiered last month, with George Clooney, Kyle Chandler and Girls actor Christopher Abbott starring.Explaining how she wanted the costumes to be as realistic as possible, Jenny was surprised to find most of what she needed on home soil, after originally being told England was the place she'd be able to pick up old army uniforms.

"Well, that was not the case.

There's little bits here and there (in England).

I'd have had to go to multiple shows year-round to collect all the stuff," she said at a recent IndieWire event, adding that she found what she needed much closer to home.

"There were hundreds of thousands of young men and boys who went to war.

Places like Western Costume, over the years, got stuff that was never used, like dead stock, or things that were collected for years, because there was so much of it.

The green (jackets) and the pants, they didn't wear that in their life very much.

Manufacturers had containers of them."Another problem Jenny faced was the difference in body shapes men of today have compared to 70 years ago.

However, the designer found the costumes were a perfect fit for the extras used on location in Italy.

"What's difficult is nobody is the same size as they use to be," Jenny mused.

"The good thing is, ironically, all the young men in Sardinia are known for being jockeys and boxers, so they are smaller than modern American men today.

So all the background (actors), it fit them perfect."
