Summer Unisex perfume?

I really want to find a great perfume for the summer, but most of the ones I have smelt have been more Fall, Winter, and Spring. The only summery one I have smelt so far has been Sun, but a lot of the reviews say it doesn't last long so I don't think I will be buying it. I could use some recommendations. Mostly looking at the black label bottles since none of the scents did anything for me instores.
