Quality tailoring begins with quality materials. This week, Peter and Derek talk to Virgil Viret, the managing director of  Lafayette Saltiel Drapiers in Paris. Their shop is a destination spot for bespoke tailors, custom clothiers, and menswear aficionados worldwide, particularly since they have an amazing stockpile of vintage textiles. Peter and Derek talk to Virgil about the structure of the fabric trade, his family's involvement in this business, and how consumers can spot quality materials.
