Inspired by the way The Uniform Project eco-transforms the same little black dress, or LBD, every day? Here comes a cute organic cotton black dress you can wear at least two ways — available now for 40 percent off!

Envi’s having a summer solstice sale, so you can get all new arrivals at the eco-fashion web store for 40 percent off by using the code “SOLSTICE” (via magnifeco). The convertible Pop Doyle Dress above is one of the new pieces — made in the U.S. out of 100 percent organic cotton — that can be yours for $56.40 after the solstice discount.

Already have an eco-LBD for the summer? Then browse Envi’s 124 other new items for the season for light organic cotton cardigans, jeans and tanks made affordable by this sale — through June 20, after which the discount code will stop working and days start getting shorter.
