I have won 1st prize for the past 4 years at 2 different beach bars here. Last year I was Martha in a jail cell. Used a refridgerator box--cut the bars into it, faux cinderblock walls, exact copy of the Camp Cupcake logo-even had a red police car type rotating light in the cell. Prison stripe outfit, etc.
Three years ago-I was a Fortune teller. Again-made my 'booth' from same size box as above-only used 3 sides, so it would fold for transport. Wired a silky curtain on the back wall, had chase lights stapled to the outline of the whole booth; neon paint for booth signs; coin slot with a metal bowl so it 'clinked' when folks put their quarter in. I would then move mechanically-reaching for the token they all got in another slot...a wrapped fortune cookie! Costume was easy-typical gypsy attire. Also had a crystal ball which I put a set of twinkle lights inside of it, which looked cool!
Two yrs ago-I made a 'life sized dummy' from a pair of leggings & a turtleneck-stuffed and a styrofoam wig head was attached to this body. I then bought a 'male' caveman outfit, added a wig, bone jewelry & then I made my 'female cavewoman' outfit-tied a rope around the waist of the male & dragged him all over, all night long. Had a big plastic prop club which I'd stop & club him every now & then. On the back of MY butt-was a sign that said "I Love Clubbin'!"

Sharon, your costumes sound great. Very creative. I can see why you won.
