I agree on many of the others opinions. This is more a beach style dress. I think this would fit great, when going on a holiday, just for a quick wrap up, when going to lunch etc.
I think, that i would prefer some more silky or smooth fabric, and maybe go for another color. Somehow I feel like white is reserved for the bride.
However, do whatever you fancy.
My recommendations would be, wear a long dress with color and not to many details.
