Preppy vintage plaid blazer jacket and skirt matching set

This is soo cute! It is a matching navy plaid set with red collar. A warm blazer jacket and a knee length skirt. The buttons are maybe the cutest part. This could not be more preppy and classic in style. Please see pictures for measurements! I think it fits like a women’s Small or size 2-4. I really do not see any imperfections on this except for some discoloration on the waistband of the skirt (which you would not be able to see under jacket).
