Vintage Ralph Lauren black velvet riding blazer gold buttons XS

Vintage Ralph Lauren black velvet riding blazer gold buttons XS. I am so sad about this as when I bought it, the measurements were off and this is way too small for me. It’s tight in the arms and I can not button it up. See photos for measurements. There is absolutely no stretch and would likely suit a size 0 or 2. I am normally a size 4/6 in most brands. Velvet is the high quality buttery soft velvet (not the cheap kind). Measurements laying flat fully buttoned up Armpit to armpit: 17” Shoulder seam to shoulder seam: 13.5 inches Top of shoulder to bottom hem: 23.5 inches For reference I am 5’7, 130 pounds, 34b/c
