The collar is hiro-eri(unfolded collar), and silk lining of the collar is added.

It has embroidered "True Tyrian Purple" on right front panel.
Besides wear on collar, stains(C,D) are noticeable.
Also there are other flaws such as snags, so please check detail photos.

However, it must be an amazing handicraft material!
