Let everyone know that you're introverted but 100% willing to discuss books by wearing this adorable crewneck or t-shirt! This item's design is embroidered onto a ****Gildan**** indigo crewneck made of 50% cotton and 50% polyester or indigo t-shirt made of 100% cotton. Crews and tees are preshrunk, so don't worry about shrinkage in the wash! For sizing information, please refer to the size chart provided in the listing. Because each crewneck is handmade by me, the current processing window for orders (not including shipping time) is 4-6 weeks. Please understand that I unfortunately am not able to offer expedited or rushed processing at this time. Do you need a size not offered on the listing? Do you want a custom color combo? Just let me know!
