The Armoury by Osaku Bone Linen/Cotton Flat-front AO Trousers (NOS)
The Armoury is happy to introduce Mr. Hayato Osaku's namesake brand, Osaku Trouser to our artisanal offerings. Like the majority of today's expert tailors, Osaku-san gained experience working for sartorial houses such as Salone Ondata and more recently, Sartoria Ciccio. While working with Ciccio, Osaku-san honed in his own designs which launched his brand into the standalone atelier he has today.
The "AO" Osaku Flat Front trouser has a mid rise, with more room in the hip, slim in the thigh, and features a slight taper towards the cuff. The AO trouser also features front and back darts to help provide a clean look and fit.
