The most important lesson I learned from this whole outfit process was: When beginning any project make sure you start with a very good base. Its always good to give a girl a personal customization to show you care. In the base game, textures that get called from a p03 file or textures that get called from the texture folder for skirts and underwear have strict size limits depending on what material they use. An interesting side quirk with the original swimsuit is that is has a very blue shadow texture and unsurprisingly it causes swimsuit colors besides blue to look terrible. Making an outfit utilize the texture folder with texture selections is achieved by simply editing material names and. While there are already swimsuits with selectable textures like the competition swimsuit and the high-cut swimsuit I am personally more of a fan of the default school swimsuit.
These outfits also require the AAU hi-res texture patch enabled in the script tab to display correctly. The outfits use slots for girls and for boys and have many tweaks regarding textures and behavior so they work in AA2. PP2 is a compressed mod file format usable only with AAU.
