This is a Harlowe & Graham sleeveless cardigan with zipper with a leafy pattern

I was unable to find this sweater on their website. I did do research to see if I could find it anywhere else that they were selling, but I could not find this at all, but the tag does say it’s Harlowe & Graham. I did measure it. I measured the length of it, and the amount of room there is when your arms meet the sides also, this doesn’t have a size. But it is super stretchy.
