I ordered this dress in both a petite xs and regular xs and the petite fit the best. for the first time in my life i did not have to shorten a maxi dress and i am 4ft 10"! 
the color is a beautiful dark blue( not sure why the color online says charcoal) and the opening at the chest area is a little low, but nothing that double sided tape can not fix.  another bonus, as other reviewers have stated,  is that you can wear a regular bra. lastly it does not wrinkle, so you can bring this on vacation
