Just a quick note about costumes for the Zoot match. In an attempt to keep it from becoming a military reenactment sport (not that I think that’s bad) Hustler prohibited all military uniforms. I convinced him to revise that to allow military uniforms if they had a relationship to the prohibition era. Some examples would be Coast Guard, RCMP or Mexican Federalies. If you want to wear a 20s or 30s uniform please be creative with your back story.
On the other hand AZSA costumes are really easy. Just about any Good Will store (you may have to hit more than one) will provide most everything you need. A bit oversized suit (single or double breasted, with or without a vest, the wider the lapels the better) will be great. If you’re going to wear a tie with that suit remember to tie it short so it ends at about mid stomach.
How about knickers, very popular in the 20’s and not just for golf but that’s a great AZSA costume as well. If you can’t find knickers any loose fitting pants bloused just below the knee with a big rubber band will give you the look. Hang them from a pair of suspenders (even I can sew buttons on a pair of pants) and you’re good to go.
Button up shirts and sweaters were popular but t shirts weren’t. As a matter of fact what the kids today call a “wife beater” was the t shirt style of choice in that time but it was also rare for someone to go out of the house in just this shirt.
Everyone wore a hat and the first thing everyone thinks about is the fedora, but remember, the snap brim (driver style) hats were almost as popular. In the west the cowboy hat never gave way to the fedora. How about a straw boater or skimmer, this was the summer time hat of choice for many a man in the 20s and 30s.
Hope that helps.
