Hey man, welcome to Basenotes. Bummer about the lack of a GF at the moment. Combine the fragrance suggestions below with pushups and a vibrant personality and you'll be set
Where do you live? You'll get better suggestions where to find the stuff we recommend.
Creed Green Irish Tweed is a big crowd pleaser. Very versatile, can be worn on dates/parties/suits/jeans/spring/summer/fall/winter. You can usually find this at Neiman Marcus, some Bloomingdales, and some Saks. Definitely try this one out, you may hit a lot of your designated targets with it. Don't buy it on ebay - too many fake bottles there.
Burberry London is a great fall/winter scent. Cinnamony, not too loud.
Le Labo Rose 31 is some really sexy stuff. Niche, not very easy to find.
Marc Jacobs Bang is new. Might be a good one to try. I like it but I don't love it. Saw some girls swooning over the scent at Bloomingdales.
Gendarme is a very safe for work scent. It's out of the shower Ivory Soap clean. Nordstrom's often carries this.
YSL Rive Gauche is a somewhat more mature scent. It's clean in a "I just got a shave and a haircut at the barbershop" sort of way.
You can get samples of all of these at theperfumedcourt.com
