Portrait universitaire classique au style preppy

Transform the SUBJECT into a character embodying a classic, preppy academic aesthetic from a period drama. The SUBJECT should be dressed in a crisp white collared shirt, a dark brown argyle or patterned knit vest, and a plaid skirt. Accessorize with a delicate pearl necklace and a stack of beaded bracelets on one wrist. The hair should be styled in a neat, slightly wavy ponytail or half-updo, with soft curls framing the face. Makeup should be natural yet refined, featuring a soft pink or coral lipstick and subtle eye makeup. The setting should suggest an outdoor school or university campus, with blurred figures in similar attire in the background and soft, natural lighting. The overall mood should be earnest and slightly formal, with a hint of youthful innocence. The composition should be a medium-long shot, capturing the SUBJECT from the waist up, with a direct gaze towards the viewer, conveying a sense of quiet confidence and composure.
