My good friend (female) just started a new job in NYC. She also put me in touch with the style editor for GQ, who mailed me a bunch of clothes for free and took me shopping. To say thank you, I want to mail her a small gift. I do have a girlfriend, so I don't want to send anything that would make her feel uncomfortable. She likes flowers, so I was debating sending flowers. That just seems overplayed though. Any recommendation?
