Vintage blazer

Very good condition Blue stripe blazer Evidence of manufacturers tag but has been cut, no material, size, or brand noted It’s thin, light, a little rough. Maybe cotton or polyester blend? 2 large front pockets, actually fits a smart phone horizontally perfectly. Slight bubble sleeve About 24” long, 22” pit to pit, 22” shoulder to sleeve Does not button together so leaves room Note there are several thread loops pulled as shown. I think they could be pulled back through but is up to new owner. This item is sold as is. Photos are part of description. Please review photos and ask questions PRIOR to purchase. Thanks!
