J B Corsets were based in Manchester and made a range of foundation garments. The Masterfront corsets were designed, so the advertisements stated, ‘on an entirely new principle, so as to ensure comfort, hygiene, and durability and meet the dictates of fashion. A notable feature is the ‘Fascinating Effect of Closed Back’. It is the closed back that gives the J.B. Corseted figure that alluring silhouette – so fashionable and fascinating.’
