Sleeveless blouse from STUDIO375. It's a beautiful green color. The gathered collar is buttoned (photos 5 and 6). The front is silk, and the back is polyester and rayon. I think it's a cute yet elegant item with a sense of formality. It's a new item, only tried on, but it doesn't have tags and has been stored at home for a long time. I kept it for special occasions, but it no longer fits, so I'm selling it. There are wrinkles, but I will fold it up small and send it as is, so please be aware of that. If you have any questions, please comment before purchasing. Thank you.
