I don't think it's deliberately that way.
First, modern fashions dictate more immodesty from women than men. That's been the norm in our society for the last 75 years or so, although it's not the first time in history that it's occurred. In an effort to maintain modesty, it would seem that women get the brunt of the rules, simply because men can wear what is normally deemed acceptable and still be both modest and fashionable.
Secondly, I think women have a natural propensity toward things that are shiny, bright, colorful, pretty, or just plain beautiful. Personally, I know I'm not particularly tempted to blow money on a new toolbox, but hold up a cool ocean blue boatneck, three quarter length sleeve cashmere sweater, and I'll have trouble holding on to my purse.
Some people over the years have seen this natural tendency as a vice, (and of course like any natural tendency, it CAN be a vice), and have orchestrated overzealous rules in an attempt to squelch this feminine quality.
Finally, and simplistically, the rules are a tad chauvinistic because men have been the ones making them up.

It's not deep, it's not complex--it's just because men don't see things the way women do, and have a sort of straightforward way of handling problems--in this case, women--and so they have these cut and dried lists that are apparently supposed to answer all the immoral issues of females around the world.
I don't think they've made up rules in such a way because they hate women or because they view them as inferior. I think they've gone about making up rules in the same way they would go about planning a wedding party. Whereas a woman is going to examine every detail, your average man would probably haul in buckets of styrofoam cups and plates, buy cupcakes from Wal-mart, cater in bbq, hook up some fog machines and call it a day.
Chauvinistic in the sense of being deliberately malicious toward women? No way!!!! Bent in the favor of men, perhaps unintentionally? Sure. Maybe a little insensitive towards women in general? Yep. Overly simplistic? Absolutely.
