Saying that, I have a friend with a few and they fit him very well - the shops allow you try on all the different cuts and sizes, so give that a go if you're unsure (and over in the UK...).
I've found Hawes & Curtis slim fit Brandon or Curtis shirts (double and single cuffed) the best on the high street - they retail higher, but will bring them down to Â£25 for sales quite often.
How large are the collars on the Hawes & Curtis Brandon shirts? It looks like the Curtis shirts have a very high spread collar, is the Brandon the same or more toned down? Also how heavy/stiff is the material? I absolutely hate thin material that wrinkles easily.
