It's a relatively easy way to look smart, which I appreciate, but I don't currently own a suit-jacket, unfortunately. Not one which still looks smart, anyway.
I'm going to have to buy a new pinstripe for some interviews in London, shortly, which'll put me in further debt, but I think it's a fair investment.
I tend to wear shirts rather than t-shirts, and my crombie rather than a more casual jacket most of the time, but not suit trousers, mostly because I don't want to wear them out, and it seems a bit odd, what with not currently having a job.
