Halloween Costume Idea.. Some type of shot(alcohol) Help!?

So I'm thinking that for halloween i want to be some kind of shot.. like a tequila shot, or on the beach, screwdriver.. etc etc. I just need some help creating it. I'm using a little black dress as the base. How can I make myself look like a shot? Like for a tequila shot i could get cotton and glue them to the top like salt and somehow put a lime on there but what else could i do to the rest of the dress to make it look more like a shot? Or any ideas for other kinds of shots are welcome too.. thanks!
