The colors are amazing. so vibrant and plentiful. the arm holes are fairly generous but not bad. i think it just adds to the loose fitting nature of the dress. i got a medium.. i'm 170 with a small chest. medium is my norm for maeve. the buttons in the back are difficult, you need help getting on, but getting off you can do solo. this dress makes your shoulders look really good!! it sits in a very flattering way.
