I never went for the carrot look (I'm way too old) but wear skinnys only because I'm a short arse with a tiny waist and skinny chinos look like a slim fit on me anyway. I have beige, red and bright blue chinos that I wear fairly frequently, which again, like you, I try and dress up with smarter items to give a sharper look.
In the summer I wore loafers a lot with them, but as the colder weather draws on it's more often than not brogues. Good smart shoes is such a great way to dress up chinos.
As or alternatives, I tend to either be in them or (more often) jeans. I have a couple of pairs of nice flat panel trousers (one in a prince of wales check and another in a dark brown with a very subtle pinstripe) which I bought in a Paul Smith sale (£20 a pair!) that are a great alternative, but I have to say, I don't wear them too often.
I have hundreds of things to choose from when it comes to the top half of my body, but my bottom half choices are far more limited. I'm considering a pair of tweedy type trousers (for the heritage look) from Ted Baker, but I suspect they might end up hung in the cupboard a lot:
So, yeah, suggestions, please!
