Gant cotton linen blend blazer

High quality sporty blazer (Polo style). Made with 94% cotton mixed linen fabric. No tag but brand new, never worn. Good with tight horse riding style pants or fluffy midi skirt/dress. So classy. Tag said size 4 but it’s very tight fitting, I would say this fits somewhere between XS and S. Shoulder to shoulder: 15.5” Armpit to armpit: 18.5”
