As far as I am concerned, as far as the people I work with are concerned, as far as the company is concerned, there is absolutely nothing wrong with that.
But yet, I was increasingly feeling ... slobbish. Like, "this is my career, this is what I do for a living, this is what I went to college for and continually read books to learn about... is this really how I want to dress?"
So I started dressing up a bit here and there. Felt silly at times, but no-one said anything. Today I'm wearing a suit-style vest and a tie. Walking in the hallways I feel conspicuously out of place, but back at my desk, I feel better about myself. I feel like I'm taking what I do more seriously. Am I really taking it more seriously? Hard to say. I think perhaps.
I don't care what you wear, and I hope the feeling is mutual. For myself, I'm kind of liking dressing up again. I don't feel that I'm conforming to any social demands or artificial constructs of what is proper; if anything, I am now going against them.
Originally I picked this style to see if an orderly fashion imposed any kind of order upon my mind. (that was about 5 years ago, give or take a year) If so, I've not been able to discern it. I did, however, enjoy feeling a little different, and over the years as my middle-aged gut expands, I find the vest far more slimming than a Tshirt.
This leaves me in the position of being a touch conformistly counter culture AND fat. Ah well.
One legitimate reason why I would expect suit-wearers to be challenged is the fear of formal wear being required in the office.
Business suits are business wear, not formal wear, which is a whole different category of clothing. Formal wear being required in the office would be a very odd thing, indeed.
"I know it's inconvenient sometimes, but you would not believe how cheap it was to rent out this extra space from the local symphony orchestra."
On one level, it seems to be a shame - suits do show a kind of respect or reverence for the place of work. On another, I think suits have their place, but as work places aim to make their offices more people friendly (some would say to keep them in the office longer) people's attires will naturally mold to fit the environment. Perhaps the dying out of the suit is something of a reflection of modern work practices and should be just seen as another item of clothing someone chooses to wear, without the significance of it being 'smart' or 'formal'.
