Looks at it this way, you get to save more money from not having to buy clothing for work as it's now provided. (or buy more of your gourmet takeaways that surely contains unfrozen meat)

Looks to be fair, until you get the uniform, and put it up for us to comment, you can't make any assumption that it's a) poor fit b) poor quality c) make you look less of an IT personnel - of which you are.
At my work, I have to go in shirt, tie and trousers. I'd be happy for an office uniform as our company actually have a set of shirt that has our logo embroiled, subtle and still distinguished, plus, we pride ourself to our Brand.
Unless your company really have a bad rep or a poor name, having the logo / company name on should be a source of pride that you're working for said company.
If I were your boss and you want to leave because of uniform, I'd rather you go than be forced to take pride at where and who you work for. If there's no work pride, what's driving you to make the company greater and better?
