I found this awesome online boutique called Kind and they have some really great, eco-friendly clothing. As you may have already guessed from the title, the philosophy of the boutique is to promote earth and animal friendly products.
They even have a pretty decent Vintage section (with sizes that aren’t completely elfin!), and the customer service is awesome. When I emailed some questions about the design and quality of the shoes, and I got a response within a few hours. Pretty awesome.
