We rolled out several new products at an annual trade show, calling it a "World Premiere." This wasn't Hollywood, but it was a big deal to us. We ran a trade show booth with attending glitz. One feature that really worked well was the logowear. An embroidery company made a die of our company logo, then stitched it onto our shirts and blouses.  

The result was fantastic, and none of our competitors had anything similar. We were worried that we might come off as the local exterminator or garage mechanic, but friends and clients loved it. Fifteen years later I'm still wearing logo shirts for appropriate occasions.
