Calm down. I don't click on any links and I find people referring to something that they put on their feet a "collection" rather strange. Six pairs is fine, but I would argue that you probably need to get both the boots and the wingtips and perhaps the penny loafers. At least that's what I did.
If the worst advice you ever received on SF is that you should have more than two pairs of shoes, you are doing well my friend.
Okay, sorry man. That was a misunderstanding. I see how if you didn't click the link, you thought I had a "collection" of one pair of shoes. And, if someone told me that, I would probably suggest that they not buy one of the RL shoes, as you suggested.
