I don't care for yellow apparel but my son's high school is black and gold and I was looking for a deep goldenrod yellow to wear to his sports events. This was not it. Reviewers were all over the place in describing this yellow - light yellow, mustard, sunny yellow. I found it to be a darker yellow that looked dingy. Not bright, not mustard. The vest was comfortable. As for size, I always wear a small in Land's End puffer vests with a little room to spare but the small in this vest was very snug without anything under it. The medium fit but was a little large in the arm holes. I am 5'4 and wear a S/4/6 in most things. Decent vest and might consider another color.
