I purchased both the heart cable knit sweater and the shamrock cable knit sweater. The level of quality in both is impeccable. Both are beautiful and I love them. However, these two sweaters are identical except for the embroidered heart and shamrock designs, yet the sizing is very inconsistent. I purchased the heart sweater in a size M and it was fine but almost a bit too big and loose, especially loose in the arms. I purchased the shamrock sweater in a small and it arrived looking 2 full sizes smaller and extremely short. I kept both as they were sold out, but I was very disappointed. I purchase a lot of Kiel James Patrick items and now I am seeing I can't trust the sizing provided. The best advice I can give is NEVER to buy the Small or XS in any sweater unless you are as short as 5 feet tall and have an A cup size. Otherwise, go with a medium or above. The online measurements just don't match the actual items. I love your clothing but please do better. There should not be an enormous size difference between the small and the medium sweaters, especially such a dramatic difference in the length. The small is almost a midriff length sweater on me and is super short, and the medium is almost a bit too loose, and oddly loose in the arms. Please work on this as I need to be able to trust the measurements you provide.
