This is the second Sakkas cover-up for me.  I like them because they are rather flow-y and comfortable to wear at the beach or even, dare I say, to a casual dinner after the beach.  They cover most of your faults and don't show too much skin.  I wouldn't say that they are dress-y, but that isn't the point, is it?  They are just beach wear that works double-duty if you don't mind it.  I wouldn't wear them without the bathing suit under, though, particularly if the color is light.  They are thin.
