I love this dress. I feel that it is a generous Medium in size. If you are the girl that can't decide on the medium or the large, then this may be your dress. I usually have problems with fit in the chest 37DD (36 too tight 38 too big) I am sure ladies with similar size understand this. I was equally concerned because it has a zipper in the back and that usually is the kiss of death. This dress didn't let me down. I also think if you aren't as well endowed that it won't look big up top. The V-neck isn't too deep but enough to wear almost any necklace. The sleeves are great with the bell and complete the look and the length is perfect. Not too long (I am 5.5) hits above the knee, but I can move freely without fear of exposing too much like some dresses. Im 49 and find that some I feel age-inappropriate, however, I am too young for other styles. I did order both the medium and the large for all of these reasons and the medium fit like a glove, so will return the large. Gotta love RETRO returns!
