I'm not looking to turn this into a big debate, but what exactly does "ethically" mean, in this context? That the suit was made in a country with a good record of upholding basic human rights? That the people who made the suit were paid in accordance with some (which?) standard? That the sheep from whom the wool for the suit is derived were sheared in some sheep-friendly manner? That the facility where the suit was manufactured uses only environmentally-friendly renewable energy? That the manufacturer donates some percentage of its profits to some cause(s) you deem desirable? That the suit's manufacturer doesn't discriminate in hiring/promotion with regard to age/gender/race/religion/ethnic origin/sexual preference/etc.?
Again, I'm NOT challenging your right to limit yourself to ethically-made suits. I'm fine with that. I'm just not sure what ethically-made means in this case, and would appreciate some clarification.
