I wear neckties whenever the mood strikes me, and I'm a Java developer. I was well into clothing before I became a programmer. I like neckties for aesthetic reasons, and the same goes for suits and sport jackets. Yes, I've been harassed for this, but I just ignore the snide remarks. If you're a developer who has always been into elegance and grooming, then check out these blogs: http://englishcut.com/ and http://asuitablewardrobe.dynend.com/.
