Founded in London’s East End in 1969 by master tailor Dave Bance, Robert Simon has a long history in British menswear.

Separate pieces are particularly useful when different jacket and trouser sizes are required or when you want to wear a suit jacket independently for a smart-casual occasion.
Robert Simon Tailoring and Style
Robert Simon’s current collections cover both timeless and contemporary tailoring, making the brand suitable for customers who want traditional formalwear without being restricted to plain business styling.
For a versatile outfit, consider classic navy, grey or neutral tailoring. Checks, tweeds, pinstripes and textured fabrics provide a more individual alternative for weddings, race days and special occasions.
