Off White Galaxy Brush Tee (read desc)

My aunt gave me this tee as a birthday present and it’s just not my style. I looked up the price to see how much I should sell for, and it was going for around $325. I took off the tags and threw them away not knowing they were worth anything. Worn once. Might be a replica because I doubt that my aunt would buy this for 325, but even the replicas are going for like 150, an this looks 100% authentic to me so I’m pretty sure it’s legit. (Fits oversized)
