I personally do not think that perfume has any age limits or rules. Wear what you want, when you want. I don't have seasonal perfumes, I just wear what smells good to me! If you like it, get it. I also love D & G light blue, and I'm not old
Well if you like the scent wear it, but heavier scents can be a bit too much on a very young woman...and many Dolce&Gabanna scents are heavy. Generally if it is very musky it's probably not the best idea for a teen/young adult.
