Thank you for looking. I purchased this on Mercari two years ago, but I am selling it because I don't have the opportunity to wear it and I am decluttering. I have not worn it since purchasing it, so please refer to the previous seller's description below. Unlined polyester, worn 2-3 times for lessons. It is not a ready-made product but was custom-made with a sewing machine. I believe it can be worn loosely. There is a faint stain on the lining of the collar, very close to the button of the wide collar. It has not transferred to the outer fabric. It is shown in the 7th photo. Size... Please check the 5th photo.
