I think what Ville brings up is an interesting topic that has caused a few ripples way back when with the older posters.
In the big picture view, everything is personal preference. So in that sense, nothing is wrong. Its your taste/money and you should wear whatever makes you happy. But if this site is to be viewed as an enthusiast community, where people come to teach and to learn, then there has to be a framework. No different than other enthusiasts communities (like watches, food etc). There is nothing wrong with a diamond encrusted Rolex, but I probably shouldn't wear it to my job interview at IBM.
Addressing Ville's post, there is a city/country difference in shoes, suits, shirts etc. There are also reasons for the differences, many of which have been hashed out here many times. If you choose to ignore them, that is perfectly fine (I ignore some myself) but you would benefit from knowing the "rule" in order to know how to break it. The great thing about classic menswear is that there is a large body of work that you can draw upon to see "correct" applications, and that the tools of our trade have remained unchanged for over 50 years. Suits/shirts/ties have pretty much remained the same for decades. You look at what people who are considered great dressers (past and present) wear and you take what you can from them. You adjust the choices to fit in with your lifestyle (unless you are a British aristocrat you probably can't get away with some of the Duke's outfits) and you start to develop your style from there. Its an evolving process, at least it has been for me. So what does this all have to do with what Ville said? Well, if there is no right or wrong and its just personal preference, there is no evolution. In that world, we are all great dressers, all of our choices are fine and there is nothing to learn. Scotch grain shoes are fine with a tuxedo, work boots with suits, captoes with jeans etc. What Ville is saying is that, historically (and presently), textured leathers are used in country settings. That does not mean that you have to be a slave to that "rule" but to say that its simply personal preference or a stupid rule, is spitting in the face of the Bruce Boyers/Alan Flussers/Duke/Cary Grant's etc etc etc.
Now I know that RogerP is not someone that I am ever going to see wearing sneakers with a suit and you do not need preaching to, so I know where your post is coming from but there are a lot of guys on here that have the "fuck it, this is my style" attitude even though they have a tremendous lack of style. WAYWN has become very similar to the AskAndy WAYWN that people here used to bemoan and that caused a lot of the Ask Andy people to come over here. There has to be more that "RoboKop!!! and everything being "Amazeballs!!!" for the forum to mean anything. Otherwise its just a mastubatory group exercise; all the purchases are great, all the applications of those purchases are great and everyone looks amazing.
Disclaimer: This is not a dig at the boots mentioned or at RogerP or at anyone that uses Amazeballs.
