Preciosa esta camiseta! Es súper cómoda y fresca para el verano, el dibujo del perro es tal cual la ilustración, muy detallado y adorable. Me gustó tanto que compré otra pero en rojo, ¡una maravilla para los amantes de los perros y las prendas con estilo!

I uploaded my photos and submitted my orders on Monday, they arrived at my door on Thursday, in California. Same week. Incredible, super fast delivery, and awesome looking t-shirts! And very much, more than reasonably priced. These photos are proof of the great work that you pay for! I’m very happy, and so is my baby girl Pecan! Thank you, TeeDiy! Highly recommended, and I will order again soon!
