Purchased at a Green Label Relaxing store. The fabric is a slightly thick and sturdy cotton. Selling as a set of two ◡̈ I loved them so much that I bought both colors, featuring a dinosaur face on the chest and patterns and logos on both sleeves! I wore these as stylish clothes on holidays, so they weren't worn to the weekday nursery. However, both have faint stains on the front. Please check the images before purchasing.
