A yearly festival in western Michigan involving only women (and the occasional gay man), with a yearly theme. (Ex. 80's prom, rave, etc.)

Lots of booze and ladylike love going on!
Decorations include banners made of bras and panties.

Men are allowed only under the pretense that they are slaves of some sort, cooking, cleaning or beer wenching.
Dude I can't wait for estrofest this year, last year's prom was awesome!
