Time to buy new clothes

Well, what the post's title says. I need to buy new clothes, and fairly soon. I don't like to do it, but sometimes it is a necessity. In this particular occasion, it is work related. My working place has a dress code and I cannot be casual. Unfortunately, I have about three wearable shirts and one of them is more than ten years old and thus not that wearable. So I must find new ones. Fortunately I am up to date with trousers. I am not certain where to go. The only shop I tolerate to do clothes shopping is the Mountain Warehouse, and only because they sell warm and comfy stuff that are hopelessly casual. Moral of the story: life is sometimes so unfair.
