Christian Dior The Suit Vintage Oversized Blazer [size 4 but fits like petite]

*This is not officially petite, but the sleeves were likely altered (by my mom, who's around 5' 2") for petite sizing, possibly the length too. See measurements.*I just discovered that the color is a very dark navy blue rather than black. It's dark in my home... But comparing it to other black blazers, I see that it's not black. That said, if it's not next to something black, it might look black.Also note that with the on-figure photos, the jacket is too small (that person would probably normally wear around a size 8 in blazers), so it doesn't fit as it should. It will look better on you!My mom’s. Vintage from the 80s, bought new at the time. It's definitely authentic Dior because she only shopped at established department stores for stuff like this. It may be from B. Altman because she worked next door (or very nearby) and went often.Oversized cut. Double breasted with low closure. There's also a button inside (like with all double-breasted jackets). Padded shoulders. Tailored, but roomy and fairly straight cut. Plum-color lining.VGUC to EUC overall. No stains. There are 2 small holes by the buttons at right cuff, a few loose threads, and 2 lines on the back where it looks like there’s a lighter thread woven in and the reverse on the label. See photos.Size 4 on tag, but would probably fit petites best because of sleeve length.Shoulders: 15-3/8”Sleeve: 21-5/8”Bust: 18-5/8”Waist: 18-1/8”Length (HPS): 29-1/8”Hem: 19.5”100% worsted woolMade in USASFPF
