The actress is experimenting with new silhouettes, styles and designers as she continues on her "year of health"

Rebel Wilson remains committed to her healthy new lifestyle.

As the Pitch Perfect actress, 40, has been closing in on her goal weight during her “year of health,” she's been taking advantage of experimenting with her style in a whole new way.

A source tells PEOPLE: “Her health journey has made fashion even more fun for her and she loves trying new things and new designers and being adventurous."

Wilson did just that when she made her red carpet debut with boyfriend Jacob Busch in September, wearing a gorgeous metallic, off-the-shoulder gown from the Rene Ruiz Collection by Luis Escudero. She let the multi-colored dress, which featured a sheer overlay and a high waistline, be the star of her ensemble by pairing it with minimal accessories and soft, side-swept curls.
