After reading the reviews on here, I ordered the dress with reservations about the fit in the arms (many had mentioned that they were too tight.) I did not have any problems with the arms, and the dress fit beautifully all over. I have a pretty proportional hourglass figure, but I am curvy and quite busty (34DD), yet the dress was so flattering and covered all that needed to be covered. I did end up ordering a size larger than normal (I usually get a 10, and I ordered a 12 in this), but the sizing seemed consistent with what was listed on the sizing chart. As for the arms, mine are 11 1/2 inches where the bottom of the sleeve hits, so if you're ordering a size 12, perhaps that will be helpful. :-)My dress is purple, and I'm very pleased with the color--a bright, true purple. The fabric is a bit see-through, but I'm a big fan of slips anyway, so that shouldn't be a problem. As others have mentioned, the fabric does wrinkle, but that wasn't a shocking surprise with cotton poplin.All in all, very cute! This was my first overstock.com purchase, and I'm very happy.
