This does not work with all swimsuits - it does work with Emu, Gimlet, Carnelian, and some others. Have your girl wear a transparent visor and lay poolside. Position the camera so that you're looking at her through the visor (the camera is over her head). Her swimsuit will be invisible, though the naughty parts are starred out.

Increasing Your Swimsuit Inventory
Since any single character can only buy certain swim suits, it can become somewhat tedious to obtain every outfit. In order to speed things up a little, team up with someone you know has a costume you would want, or one that your teammate does not have yet. Once you become better friends, anything you give her as a gift, in this case a swimsuit, she will keep. The key is to make sure she is at least somewhat happy with your performance on the court. After you give your teammate an outfit, it is most likely you will get one as thanks when you return to your room the next evening
Unlock the "How Crazy Are You" (by Meja) and "Is This Love" (by Bob Marley) music by finishing the game one time then starting a new game with that saved game.

Give Any Girl the Venus Swimsuit
Play as Lisa and win about 1,500,000 credits playing volleyball. Buy the Venus swimsuit then start a new game. Lavish the desired character with gifts. After the character in question starts to give you a lot of gifts in the hotel, lay the Venus swimsuit on her in the morning. Next, buy her a couple more gifts -- one that she will really like and one that she will dislike. Start a new game with the character you gave the Venus swimsuit to, and it should be in their inventory. Play the game as Lisa and earn 1,000,000 credits. As you are earning the money, start giving the person you desire gifts that she really likes. Wait until the music notes start to move rapidly. Once you have enough to buy the Venus, wait until evening to give her the swimsuit. She has to open it in front of you.
