This is a tweed, collarless short jacket purchased from BABYLONE. It's a very elegant piece of clothing, as it incorporates gold lame thread. I've worn it about twice, and it no longer fits. Would this be suitable as a light jacket for the upcoming ceremony season? - Color: Gray系 (Gray-based) - Design: Collarless - Material: Tweed-like - Style: Short length - Pockets: Front pockets Thank you for looking.
