Per aspera ad astra

Since you all know I'm going quite far from home and I will have the possibility to get a perfume for a special sale only here (mum knows the right people who reduce the prices hehe!),  I was wondering if you could give me some suggestions!

I want to get something fresh (maybe even with a kind of tropic aroma). Now I'm using Jennifer Lopez' perfume Live, though it's not quite long lasting.

So, maybe you could suggest any brands that I would like? I'll be going to the mall to try perfumes anyway, but maybe you know anything that smells special :)? Like I said, I'd like to get something fresh.
