Ralph Lauren Women's Size Guide
Fit Summary
Ralph Lauren is a US iconic classic preppy premium brand using US sizing as base standard for women’s tops. Women’s styles include signature polo shirts, tailored woven blouses, fine gauge knits, cashmere sweaters, cotton tees and relaxed linen tops, available in Fitted, Classic and Relaxed silhouettes. Classic regular-fit pieces generally run true to US size; fitted polo styles have a neat tailored cut, while relaxed linen and oversized knit sweaters feature generous comfortable room. Cotton and pique knit fabrics have mild elasticity; non-stretch woven and luxury wool blends have minimal give. Fit varies noticeably between slim tailored polos and roomy oversized cashmere pullovers. Shoppers selecting non-stretch woven button-down styles are recommended to size up for extra comfort.
