Proportion London

What Proportion London does

Proportion London is a UK-based specialist manufacturer of display mannequins, bust forms, and retail display equipment, operating as a brand under Kesslers International Ltd. The company traces its heritage to Siegel and Stockman, founded in France in 1867 by Frederick Stockman, with British trading beginning in the early 1920s. It runs a 400 m² London factory in Highams Park that operates alongside the parent group's 38,000 m² facility running 24/7, producing handcrafted mannequins using a combination of Victorian papier-mâché techniques and modern materials including fibreglass, EcoForm (a biodegradable/compostable composite), wood, and fabric coverings. The product portfolio spans full-body and torso mannequins in male, female, and children's forms across more than 15 named collections (Series, DNA, Theory, IAM, Boudoir, Vintage, Harlequin, Fluid, Fashionista, Metropolitan, Mademoiselle, Monsieur, Workroom, Accessories), plus display accessories such as bust forms, clothing rails, hanging systems, and jewellery necks.

The company serves two primary verticals: high-street and luxury fashion retailers (with named customers including Harrods, Paul Smith, Chloe, AllSaints, and Ben Sherman) and museums/exhibition clients (including the Victoria and Albert Museum), where conservation-grade materials are used to protect delicate textiles. Revenue is generated through three streams: one-time sales of standard collection mannequins, transaction-based mannequin hire for short-term retail events and exhibitions, and bespoke design and manufacturing services for custom requirements. Distribution is sales-led via direct website e-commerce and a consultative sales team, supplemented by PDF catalogues, content marketing, email newsletters, and trade show presence (EuroShop 2026). The EcoForm sustainable mannequin range, which reduces carbon footprint by 96.63% versus traditional fibreglass, is positioned as the flagship differentiator and is the default material for the upcoming EDIT range.
