Ralph Lauren began as a collection of ties in 1967. 40 years on Ralph Lauren is more than a fashion brand but a lifestyle label and is synonymous with a grown up take on preppy-cool All-American style. Modern and slick but with a strong sense of playful, Ralph Lauren combines casualwear and eveningwear, elegance and quirk perfectly. Lauren by Ralph Lauren is a young and polished take on the heritage brand and offers strong seasonal styles. Browse the collection of women's Lauren by Ralph Lauren nightwear and choose from luxurious shawl-collar robes, floral-print pajamas, silk sleep shirts and plaid sweatpants.
