I usually have pretty good luck with FN but this shirt was totally off!! It was OS however when it arrived it looked like it had shrunk or was missing material. I’m not a heavy girl but I wear a normal size medium. The sleeves were not as long as pictured, They are more like 3/4 and it’s like a total crop top so it does not look as long as the picture for layering which looks silly unless your wearing very high waisted jeans. Finally this is final sale, so now I’m stuck with it! So disappointed!
