Taylor Swift Holiday Cardigan Gray/Green

In great shape! I bought this second hand so I’m not sure if it’s authentic or not. The tag looks like it was cut out (see photos) so I can’t confirm :/ I priced it accordingly since I wasn’t sure (in between dupe and authentic prices) Was hoping it would fit me but I’m absolutely swimming in it! Would say it’s probably a size Md/lg. but could easily fit a xl! Feel free to let me know if you need any pictures or have questions!
