BDP would get a little stifling on a hot day unless applied very lightly (to the point of "may as well not wear it").
For what it's worth, as we start warming up I'm using these more and more.
Creed Virgin Island Water (can't miss, cools you down)
Clinique Happy (wonderful images of oranges and nice weather)
Calvin Klein Euphoria (all-around inoffensive, but go easy on the trigger as it warms up)
Ralph Lauren Romance Silver (fantastic frag for a hot night in every sense of the word)
Tommy Bahama Set Sail St. Barts (new one to my collection but I think this'll work as a poor man's VIW)
Thierry Mugler B*Men (haven't tried this on a hot day yet but I think it'll work)
Aramis Havana (applied a little lighter than I would in the winter, this stuff works amazingly well on my body when I sweat)
