Black trench coat from Banana Republic. It has a removable quilted liner, so you can wear it year-round except in summer. The size is XS, but it's an American size, so I think it's equivalent to S-M. Approximate measurements when laid flat: length 84cm, width 42cm, shoulder width 40cm. I've worn it with care, so there are no noticeable stains and it's still in good condition. It's a convenient item that can be used for business, everyday wear, formal occasions, and more. Thank you.
