Robert Simon London at SIRRI

Discover Robert Simon London at SIRRI, with men’s and boys’ tailoring ranging from classic formal suits to distinctive contemporary designs.

Founded in London’s East End in 1969 by master tailor Dave Bance, Robert Simon has a long history in British menswear. The brand developed from traditional tailoring into a design-led suiting business, supplying London retailers and building its reputation around attention to detail, materials and craftsmanship.

Today, Robert Simon continues to combine this tailoring heritage with contemporary fabrics and styling.

Robert Simon Men’s Suits

Explore Robert Simon men’s suits at SIRRI for weddings, business, prom, race days, celebrations and other formal occasions.

The collection includes three-piece tailoring alongside tweed, windowpane check, textured, jacquard and more contemporary styles. Depending on the design, SIRRI also offers selected Robert Simon blazers, waistcoats and trousers separately.

This makes it possible to choose a complete coordinated suit or use individual pieces to create a more flexible smart wardrobe.

Robert Simon Boys’ Suits

SIRRI stocks an extensive selection of Robert Simon formalwear for boys, including three-piece and five-piece suit sets, tailored-fit styles, tweed, checks, textured fabrics and traditional formal colours.

Selected designs are also offered in alternative fits and sizing options, giving families more choice when dressing boys for weddings, page boy duties, Holy Communion, prom, Eid and other formal celebrations.

Always use the measurements on the individual product page when selecting a size, as the fit can differ between collections.

Robert Simon Blazers, Trousers and Accessories

The Robert Simon selection at SIRRI extends beyond complete suits. Browse blazers, waistcoats, smart trousers and selected accessories to create a coordinated outfit or refresh an existing suit.

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.
