This is a single-breasted suit from DURBAN's Made in Japan MONSOON collection, designed for the midsummer season. It features a center vent and double-cuffed (3.5cm width) trousers. This is a great suit. It's cool and comfortable for midsummer wear, made with 98% wool and 2% mohair for a soft feel and excellent color. The simple dark gray color subtly shifts to a blue-gray depending on the light. I've noticed people nearby staring at the fabric while I've been wearing it, which is quite interesting. The size is AB5, but the clever tailoring gives both the jacket and trousers a slim silhouette. I haven't worn it many times, so I don't think there are any noticeable stains, but it has been dry-cleaned just in case. There appears to be a slight crease from ironing on the outside of the knee of the trousers, so please refrain from purchasing if this concerns you. Approximate measurements (measured by hand, so please allow for some error): Jacket: Shoulder width approx. 44cm, sleeve length approx. 57cm, pit-to-pit width approx. 52cm, length approx. 71cm.
