Vintage Handknit RENNY Sweater

Hi! I have a beautiful handknit grandma sweater. The sweater is the vintage brand RENNY and has been stashed in my closet for months. The colors are vibrant and the only issue with the sweater is a string has come loose as shown in the second image. The tag states it is a size small, but It could fit a size medium perfectly as well. Feel free to ask me any sort of questions, and I’ll be sure to answer them. The price is negotiable of course and all offers are considered. Thank you for looking!
