Thank you for viewing. The details are unknown because the tag is missing, but I believe it is a size M product from Wacoal. There is a place where the thread is broken on the lace part of the shoulder. * No comment, immediate purchase OK * For those who understand that this was worn by family and stored at home, please consider purchasing. * Please note that as this is a used item, there may be fine scratches or stains that are not noticeable.
