I ordered one of Whitney's, from I Wore Yoga Pants To Work, long sleeve shirts because let's get real the saying is just perfection! The shirt fits great, and I love the material. It's not super heavy and not super thin. I would say it's the perfect light weight yet sturdy material. It was a limited time shirt, so I do not think you can get it anymore :( BUT you can shop her Etsy store for some other really cute shirts and koozies.
All opinions shared are my own - straight out of my roaming brain.
