Ralph Lauren US to UK Size Guide
A Ralph Lauren US size 6 is equivalent to a UK 10. The standard conversion is simple: add 4 to the US size to get the UK size. So US 4 = UK 8, US 6 = UK 10, US 8 = UK 12, and US 10 = UK 14. For EU sizing, Ralph Lauren follows standard European numbering — a US 6 is an EU 36, US 8 is an EU 38, and so on. This conversion applies across all Ralph Lauren women's lines including Polo Ralph Lauren, Lauren Ralph Lauren, and Purple Label. Men's sizes use letter sizing (S, M, L) which is consistent across US and UK markets.
How Ralph Lauren Sizing Varies by Line
Ralph Lauren operates several lines with slightly different fits. Polo Ralph Lauren offers three main fits: Slim Fit (closest to body), Classic Fit (standard), and Relaxed Fit (roomiest). Lauren Ralph Lauren, the more affordable line, tends to run slightly more generous than Polo. Purple Label, the luxury tier, uses Italian-influenced tailoring and may run slimmer through the torso. When converting sizes between US and UK, the numeric conversion stays the same across all lines — only the fit silhouette differs.
Tips for Shopping Ralph Lauren Online
When ordering Ralph Lauren from a US site and shipping to the UK (or vice versa), check which sizing system the site uses. US sites list US sizes, while UK/EU sites list local sizes. Use the numeric conversion table above to find your match. If you're between sizes, Ralph Lauren's Classic Fit runs generous, so stick with your usual size. For Slim Fit, consider going up one size. Ralph Lauren rarely offers free international returns, so getting the right size the first time saves hassle and shipping costs.
