Best perfume for me? Summer and winter?

I'm 14 and going to 10th year after the summer, and I want a new perfume that fits me. I used to use Burberry's the Beat, but it started smelling too sweet and sugary. I like scents that remind me of beaches and summer, but I kind of want 2? One for winter that smells.. intoxicating, I guess, and one for summer that smells like the ocean. I'd want them to be cheap (no more than $50 each) and not all sophisticated because I am just a girl. I like: Vanilla, citrus, almonds (I love those!), fruit, some flowers, like lilac and saffron. Alrighty thanks everyone!
