On Irff, Biggs Darklighter and Jek Porkins were seen sporting swimsuits.
Swimsuits can be defined as articles of clothing designed for use during swimming activities. When Padmé Amidala and her handmaidens took to the waters in Naboo's Lake Country, they donned these garments.
It was also common for people to wear swimsuits while on holiday at resort worlds such as Marquinn and Irff.
