To a point. I haven't been around long so from my perspective there are some accepted styles that the group-think-consensus has deemed good and others not as good, and this has everything to do with preconceived rules and regulations.
You could certainly point out some styles of "acceptable" swd fits and a formulae for achieving said look. Lets see... slutty white tee, jeans that fit just so, etc...
I'm not trying to start anything but, well, you haven't been here very long. While there's usually an SWD "look" that's in favor, it has been pretty variable over the years. Heck, even I remember the workwear heyday, and I'm by no means an old-timer. Raf, Jil and Hedi were the forum darlings for a long time, and it's only pretty recently that the golf ninja and blazer/tee looks have become more prevalent. Rick looks used to get dismissed pretty handily, to say nothing of Damir's early stuff.
If you take a look at what's being posted these days, it really runs the gamut from updated "workwear" to a nouveau grunge to tech-ninja to the SZ-look,however you want to describe it, to the sort of generic slim-casual Euro stuff that's been inspiring new posters recently. Where the beginner's outfit used to be CP's, Dior, BoO and Sterlingwear, now we've got people yelling about side zips, blazers and leather. We're edging closer to golf ninja at the moment, too, although I suppose we'll see how long that lasts.
What's notable is that it's a lot of the same posters (we've lost plenty, of course) who have been here the whole time, and who appreciate all the diverse styles of SWD without bitching about change or whatever. Frankly, I think the best posters on the forum are those who have an interest in "both sides of the wall. As Dlester pointed out in the suits and blazers thread, what's interesting about SWD is that there isn't a hard and fast set of rules to follow, and things are judged on whether or not they 'look good' vs 'looking like an idiot.'
I guess what I'm saying is that a lot of new posters tend to lament the narrow-minded ness of SWD when really, they just don't look very good. Again, not a personal slight at all, but something I've noticed generally. SWD is a whole lot more accepting than people make it out to be.
