The introduction of a dress code limiting the cleavage of lady chess players at first seems repressive.
Understand the specifics, from the writeup in Chessbase News:
Décolletés are partly covered in our regulations, which state that in respect to shirts the second from the top button may also be opened, in addition to the very top button. But, nothing is written in our rules about the length of skirts or dresses. There are several special rules in some companies which put restrictions on the length of skirts and dresses —no shorter than 5-10 cm above the knees for example. I can see that there are many players here who wear very short skirts. It's nice to see chess players with short skirts—they are very pretty girls. But I believe there should still be some limit. [...] I just want to say that I heard many comments from spectators, coaches...
But maybe the ban works on a second psychological level—your first reaction, when you hear of the ban, is to think, "Oh, I didn't know they had that problem in chess! I was in the chess club in third grade with Cindy McGee, who was then a little tomboyish, but she shared all of my interests, and we could have been best friends, but I spurned her to chase after some fourth-grade harlot, who switched schools when middle school rolled around, and by then Cindy was so tall and glamorous and I was still playing chess but there were no girls around, and, man, if only I had known. Oh, right, what were we talking about, glamorous chess players? I didn't know they had that problem!" But you now think they do, and so you begin to pay attention to women's chess, like all those lecherous rubes who crash GoDaddy.com during every Super Bowl. You read this article, didn't you? It's working already!
