The casting room buzzes with anticipation as Willa, a vision with her long, black hair, enters. She's a picture of youthful exuberance, ready to slip into a variety of swimwear. First, a playful, neon yellow bikini, then a sultry, strapless black one-piece that hugs her body like a second skin. Willa's confidence grows with each change, her fingers tracing the edges of the fabrics, her hips swaying as she struts her stuff, the room filling with her giggles and the rustle of fabric.
