I started the hobby at the very end of the summer, but I know now since I own some of these that they would make good summer fragrances:
Orange Sanguine by Atelier (if you want to smell like oranges in the most literal way)
Millesime Imperial by Creed
Green Irish Tweed (best in spring I would assume)
HM by Hanae Mori (I wore this almost exclusively last summer, now I'm pretty tired of it)
Original Vetiver by Creed
Oh, and Selection Verte! HOW DID I FORGET THAT!
