Glory, it would help to see it on to judge the scale of the print. Impossible to say, otherwise.
My thoughts, FWIW:
It will look most current this year (with florals and photographic prints being trends).
However, its black/white/grey colour will make it versatile and give it some lasting power. You can wear with white, bright, or black/ ink toppers. You can put a light sweater over it and make it a skirt.
If I bought a dress like this, at this price point, I'd be aiming to get about 2 summers from it, with about 4 or 5 wears per summer. That's just my private inner girl-math talking -- there is nothing truly analytical about it because I haven't even put it in the context of my overall budget or needs...or anything. Just a sort of hunch thing. You know..."It's not expensive, I have this and this and this occasion to wear it to, and it is a fun way to play with the trend." So then, if I wore the dress as much as anticipated, I'd be down to about $3 per wear by the time I donated.
Then again, it might turn out that I was wrong -- maybe I'd only wear it one summer and be sick of it. But to get sick of it, I'd probably be wearing it more -- maybe once every week or two all summer. In which case I would still be at the same CPW.
