What do you need to make a lifeguard costume?

To create a lifeguard costume, you'll need a red swimsuit or shorts, a white tank top or T-shirt with "Lifeguard" printed on it, and a whistle. Accessorize with a lifeguard rescue buoy and a pair of sunglasses for an authentic look. Optionally, a visor or hat can enhance the theme. Don't forget sunscreen for added realism!
