I haven't had a chance to wear it, so it's been stored at home. I have an IENA wool coat in size 40, and I tried on both sizes 36 and 38 of this down coat. I think size 36 will give you a neat and tidy fit. Non-smoking, no pets. WOOLRICH / Woolrich IENA Special Order Coat Down Coat (with included bag) IENA Special Order Color: Black Size: XS (36 in IENA sizing) Width: 60cm Length: 97cm Sleeve Length: 79.5cm Cuff: 22cm Materials: Outer: 100% Nylon Lining: 100% Nylon Filling: Protruding part on the back side: 80% Down, 20% Feather Filling: Other: 70% Polyester, 30% Wool Product Description: Selected from the men's collection and remodeled with a volume and silhouette that women can wear. I wanted a down jacket that could be worn casually every day, so I created this special order. While having a trendy, voluminous silhouette, it's a hybrid outerwear that combines a neat fit and functionality. The outer fabric is a breathable and waterproof nylon material with a cotton-like, elegant feel. Based on a functional material with excellent heat generation and quick-drying properties, natural down is combined in a tube shape to achieve effective heat retention and breathability. It creates a comfortable environment inside the garment. The built-in hood and collar are integrated, and the design is also attractive because it doesn't get in the way when stored.
