Ralph Lauren

Gosh! It's complicated. Hope it helps.

In 1967, Ralph Lauren establishes the Polo label with an instantly successful line of ties. In direct opposition to the narrow ties and conventional styles of the time, Lauren designs wide, handmade ties using unexpected, flamboyant, opulent materials. The ties quickly become a menswear status item.

Ralph Lauren Purple Label

It includes ready-to-wear suits and sportcoats (made by St. Andrews and Cantarelli), dress shirts, sportswear, accessories, and footwear, as well as a collection of made-to-order suits, sportcoats, shoes (made by British company Edward Green), dress shirts, exotic skin luggage, small leather goods, and jewelry.
