all my suits come from M+S.*
Wouldn't go above that personally, as I only ever wear them 2-3 times a year at weddings/funerals/interviews.
I guess if I worked every day in a suit then I would probably bother to purchase nicer ones..
Not because I care personally, but because others care, and the opinion of others is always important in work/life/business.. Unless you are a complete trend setter/visionary, but I am not arrogant enough to think of myself as someone who can rise above and self define away from other opinions and judgments.*
Anyway.. brought a 40 pound pare of shoes the other day.. bit pricey but hey, got to live a bit. *
