I like this dress but was disappointed it didn't have pockets. I've come to expect those in Mordenmiss dresses!  Also, it is very simple. No detail other than the tulip shape. If it's navy, then it's the blackest navy I've ever seen.  Based on the many Mordenmiss items I've bought, I think this dress should be $29.99, not $39.99.
It fits me perfectly, but pay attention to the bust and shoulder measurements.  It is fitted through the yoke and if you are and XL or bigger based on shoulder/back size, this dress might be tight. It flows out over the bust, so if you are smaller through the shoulder but bigger through the chest, it should work.  The armholes are plenty big, but again, potential tightness is through the upper back.
I think I will wear this dress a lot.  The color makes it opaque but the fabric is light -- perfect for hot summers.  I'm 5'6", ~160.  The length is good -- covers the back of my calves which I like.  Wish I could sew -- I would put pockets in it.
