Lurking or posting with any regularity will completely skew what you perceive as a "normal" amount to spend on a designated piece of clothing.
I was shooting the shit with some buddies tonight and the topic of shoes came up. None of them could justify ever spending more than $100 on shoes, even those of the well-made formal variety. I haven't dropped much on dress shoes, but would certainly do so if my budget allowed. That wasn't the case in my pre-SF days, where I actively was looking to not exceed something like $50 or $60 for those foot needs.
