This is a navy blue blazer from Ralph Lauren. It's a girls' blazer. I purchased it at a local department store about 13 years ago for my daughter's graduation ceremony and have stored it in a closet, hanging it up, for a long time. It was only worn once, for the graduation ceremony. Size: Labeled size 150 Length: 56cm Width: 38cm Shoulder width: 36cm Sleeve length: 57cm Thank you.
