Sweeney solidified the peplum trend even further at the Variety Power of Young Hollywood Event in Hollywood on Aug. 10. Taking a page from her fellow actors' styling books, Sweeney arrived in a three-piece leather dress, which included a corset top, a peplum belt, and a midi skirt over semi-sheer tights. As the corset cinched the waist, the unique belt accentuated the hips, creating a dramatic silhouette further amplified by the skirt's thigh-high slit and zipper detailing. She completed the ensemble with pointed-toe heels.
