This is a STILL BY HAND original bonded material stand-collar coat. The exterior is a crisp, firm material, while the interior is a glossy satin finish. It has an elegant, relaxed A-line silhouette, and you can wear thick knitwear or fleece underneath. The coat itself doesn't have much insulation, but it is highly windproof, so you can wear it not only in spring and autumn but also in mid-winter if you wear warm clothes underneath. Size 48 For reference, I (171cm tall, 60kg, slender build) wore it with a relaxed, oversized silhouette. Also, I wore fleece underneath in winter. (The sleeve length is just right) It feels like a general M to L size. *The following are rough measurements by a non-professional. Length: Approximately 97cm Sleeve length: Approximately 60cm Shoulder width: Approximately 47cm Width: Approximately 57cm (The A-line shape widens slightly towards the bottom) I purchased this around 2017, and I haven't worn it much, so it's in relatively good condition, but I found a stain like a scuff mark on the fold of the right collar when listing it this time. (See photo) It's not very noticeable due to the glossy material, but please be aware of this. Thank you.
