Rietbergh is a Dutch fashion brand founded by Daphne Rietbergh, Rutger Rietbergh, and Ferry van Middelkoop.

Rietbergh is originally a bespoke suit brand, specializing in the design of custom-made suits, wedding suits, and tuxedos. You may recognize Rietbergh products from the clothing worn by the newsreaders of the NOS Journaal (Dutch news program) or the presenters of Wie is de Mol (Wie is the Mole), Jinek (Jinek), and/or RTL Boulevard (RTL Boulevard). Besides bespoke suits, they have recently expanded their range by launching their own ready-to-wear line, including (made-to-measure) jeans, shirts, merino wool sweaters, and even their own eau de parfum. These are available in-store, of course, but also in their recently launched Rietbergh webshop.
