Vintage Sateen Black/Pink Floral Christian Dior Robe with Lace Trim

Originally from Saks 5th Ave, I believe this is probably vintage from the 1980's or so based on the tag and fabric print. 100% polyester but it's a very nice sateen weave, so it feels silky. Sleeves are about 3/4 length with a cute flower detail on the lace. Maxi length, total length from base of neck to bottom hem is approximately 54.5". Sleeve length from armpit to hem is about 14" (includes the 3" lace hem). One flaw is a small hole at the left armpit where it appears the fabric just sort of frayed at the seam (last 2 photos show it from the interior and exterior), I honestly never noticed it until I was taking measurements. Only getting rid of this because I have another vintage robe that I prefer more than this one and I feel like this is so beautiful that it deserves to be worn more.
