1. They're total porn for women. I think it's pretty accepted that women don't have the same need to observe the naked male body that men have to observe the naked female body, but who doesn't like a little eye candy in the form of a well-dressed man? These magazines offer page after page of menswear ads and articles featuring, yes, men in dapper suits and ensembles that nobody I know could ever afford or pull off, beautiful cashmere sweaters and tweeds and carefully tailored wool suits (complete with pocket squares), etc. Nice. It's the next best porn-for-women to, well, Porn for Women.
2. No articles on losing weight, craft-making, kids, or how to better your life by having a cleaner house. Also: no "inspirational" articles, and nary an Oprah opinion in sight. All of these things seem to be staples of "women's magazines."
3. God help me, I love cologne ads. I don't really like cologne on men, but I do like my magazines to smell musky and spicy. It's festive.
So yes, people always look at me a bit strangely when I check out my piles of these "lads' magazines" at the library. I just tell them they're for my husband (although he usually steers pretty clear of them, preferring his copies of Wired and Kiplinger's).
