USD 495

Alert me when back in stock

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.
