I'm 22 and I'm also at university.
All the fragrances you mentioned are actually in my wardrobe.
Chrome would be great for university.
l'Eau d'Issey and Envy would be great for a party.
I would advise Rive Gauche if you need to give presentations in a suit.
You might wonna try La Nuit de l'Homme and Body Kouros.
