Versace Dreamer is one...i love the smell, inexpensive, longevity, projection
YSL Rive Gauche - same as above but some might call it an old man cologne but i don't find that to be the case
Rochas Man - GREAT smelling fragrance, lacks projection which might be good for a classroom but long lasting.
Hey, other people on this site probably won't be too happy with this recommendation, but for a high school or college kid, get Abercrombie Fierce. If you want compliments from girls your age, get Fierce. They love it. I am a 21 year old college student and sadly they still love Fierce. I have worn some very nice fragrances (Aventus, GIT, MI, Tobacco Vanille, LIDGE, Le Male, DHI, among many others) and nothing gets me compliments like Fierce does, as much as I hate to say it.
If you are against Fierce, others recommended Rochas Man, Boss Bottled, and La Nuit de l"homme which are also good choices (I have all three and like them all).
