Hand Knit Cardigan Sweater Blue Long Sleeve 1X 2X

Item is beautifully made. Pictures do not do it justice. Made by a seamstress that also loved to knit and does beautiful work. Long Sleeved sweater & collared. Sweater has two sets of button holes, but buttons were not added. Pretty pattern in a medium blue with metallic threads. Also has pockets. It measures 24" across at under arms. 30" from shoulder seam to bottom hem. 21" on the sleeve length. We believe this would be a size 1X or 2X. Hand wash cold & dry flat. Questions welcome.
