Established on Jermyn Street in 1993 by Oliver Spencer – who went on to set up his eponymous menswear label in 2002 – Favourbrook was founded on Spencer’s passion for unusual fabrics.

Now with its flagship store on Pall Mall, the brand is renowned as one of London’s most prominent purveyors of partywear. The Petersham Embroidered Single Breasted Waistcoat features intricate embroidery and mother-of-pearl buttons.
