                  Numbers of monarchs have drastically decreased over the last 20 years, but together we can help bring awareness to this important topic! #monarchsmatter

                  Capsule Wardrobe FAV!

                  These tees are my new favorite shirts for my capsules wardrobe. I wear tees and jeans or leggings and I love how long these are! Perfect for every day and all seasons, just throw a jet jacket or cardigan sweater over it. The messages are excellent and I love what Nature Supply Co stands for. I ordered 3 more to complete my weekly wardrobe.
