Illustrate Doña Paquita (Francisca), a character from 'El sí de las niñas

Illustrate Doña Paquita (Francisca), a character from 'El sí de las niñas' by Leandro Fernández de Moratín, in a high-quality image with a style reminiscent of 18th and 19th-century book covers. She is a young woman in her late teens, embodying innocence and grace. Dress her in the modest, elegant fashion of the era, with a simple but refined gown in soft tones. The overall aesthetic should evoke the timeless charm and delicate beauty of classic literature illustrations."
