What about higher end resale shops? We have a few in St. Louis and they have a great selection usually. Plato's Closet, the Scholar Shop, leap to mind. I keep finding amazing pencil skirts from the 60's and 70's which look like they came straight out of J. Crew.

At least when you're buying used you are not adding to the problem. Just a thought!

I wear a lot of patagonia clothes to work. They have comfortable skirts, cute tops, and gorgeous sweaters and I *think* their materials are all ethically produced etc. You might want to check that out though.
