Well... You are 14 and you said you own 30 designer fragrances and you want something more refined, deeper. I think I know what you mean, looks like you have a lot of common designer fragrances and you want masterpieces right?
Well we have a lot of points to talk about here. When we talk about "teenager frangrances", we talk about fragrances that are cheap and still have good performance, non agressive, safe buys etc... You will always see the common stuff on the Top 10-5 fragrances for teenagers (acqua di gio, one million, cuba gold, 360red, nautica voyage, tommy, a&f fiece, etc).
I don't think we can see refined, deeper, masterpieces recommended for teenagers. But I don't agree with "age restriction", "age recommendation". I think it has to do with your maturity, your personality, what/how you are dressing and the place/event you are going to. You are 14 and you wear angel men, I'm 16 and I wear angel men too, it's one of my favorites and all the reviewers recomment it if or 21+, 25+.
Now answering your question, IMO the type of fragrances you are asking for are not rated as "teenage fragrances". But anyway, I checked you wardrobe and you should try guerlain, chanel, dior or even the niche. But keep in mind that you have to think about what situation you are going to wear this kind of fragrance. When I was 14 I didn't use to go the the places I'm going now,I didn't use to go out with the people I'm going out now, just 2 years later.
