I don’t think it’s either a good or bad thing. It’s just another adjective.
I have a wonderful friend (male) who is far more “girly” than me. He turned me on to MAC lipstick and tweezerman tweezers—two of the best beauty items in my (very limited) arsenal. He has mad makeup skillz and I surely do not.
I have two daughters. If you asked them – neither of them think of themselves as “girly”...but they both have friends within their group of buddies who they wouldn’t hesitate to describe as “girly”. It’s about what your interests are.. and if your interests are fashion, makeup, and other aesthetically pleasing things (e.g. color schemes, style, what Kim Kardashian was wearing)..then maybe you identify as “girly”.
A corollary: at my house we call it “being princess-y”.. and my husband uses it to describe me when I don’t feel like “roughing it”. He grew up in a farming family and didn’t seem to mind when, on a recent Cub Scout camping trip, they all ended up pitching their tents in a mud pit. They had mud caked from knee to toe for the whole weekend and they were all just fine with it.
Me, not so much. I “tough” it out at Girl Scout camp each summer but we’ve always had a roof over our head, and screens to keep mosquitoes out.. and camp cots or mats to set our sleeping bags on. This past year I brought lots of snacks (including cookies and crackers I wanted to eat) remembering we had hungry girls who hadn’t eaten enough dinner the years previous.
In my hubby’s book..this is “high maintenance” or “princess-y”...but oh well. Call it what you want – but that’s the extent of the “roughing-it” that I want to do.
