Holy cow I love this dress!!!  Looks perfect on right out of the box!  The bodice is very stretchy and starts fairly small so if you are ordering a size up,  the bodice should still fit snugly.  I was expecting it to be much smaller but it is true to size with a lot of forgiveness in the touched back.  For reference I am 5'11",  US size M/L,  I ordered a large and the dress fits perfectly and hits right at the bottom of my knees. I might add some ribbon ties in the back for that extra "grab" in the middle,  its not loose,  but its not very tight.
