I never had a job with a full body costume but I had plenty in the “embarrassing uniform” category. The worst was the pizza counter in a grocery store. I was an “Italian chef” complete with red, green and site patchwork “shirt” that had a sewn on apron. Of course it came with a big poofy chef’s hat. At least I didn’t have to wear a big fake mustache like the dude in the logo I was dressed as?
