Revanche Denim Spaghetti Strap Racerback Tank Top

This Brazilian Revanche denim halter tank top with metal rings in the back. I'm not sure on the size because the tag does not say and the measurements don't match most charts. Seems like it would be for a busty medium 🤷🏿‍♂️. Also please provide any info you may have on Revanche, maybe you'll get a discount 💁🏿‍♂️. Measurements: Chest: 19" Length: 26" All questions and competitive offers are welcome.
