Stand up straight and maintain good posture as you make your way across the stage. Keeping your head held high and your shoulders upright gives you a look of confidence and helps show off your body. Never underestimate how your body language can influence other people's perceptions of you.
Walk with an attitude, using a small stomp to emphasize each step. Think of yourself as a model walking down the runway, exaggerating your attitude with sexy body movements. A defiant strut suggests sassiness, which the audience is likely to find entertaining.
Allow yourself to become entranced by the music that is playing during the wet T-shirt contest. In order to dance well, you need to feel the beat of the music and let your body move naturally to the rhythm of the song. You most likely won't be able to pick the song, so be ready to dance to whatever song the DJ plays for you.
Smile and express a positive attitude while you are dancing. This will show that you are having a good time and will encourage others in the audience to smile, too. Smiling is also sexy and inviting, which will attract the crowd to you and encourage audience members to vote for you as the winner.
Keep dancing throughout the wet T-shirt contest, even when it's not your turn. This will keep you in the mood to dance and also shows support for the other contestants. You will most likely be standing on the stage the entire time, so the audience will be able to see and judge you even when it's not your turn.
Dance as seductively as possible while the water is being poured over your T-shirt. Move your hips rhythmically, and tug the bottom of your shirt so that your wet tee clings to your chest. This is your big moment, so make the most of it!
