Express yourself through a t-shirt that you have customized and had made for you. What would you want it to say? You can go as simple as saying “A Baby on Board” or make it as detailed as you would like.
I know I would love to have one that has a big bright colorful peach on the front and a scripted Peachy on the back. What color would I use? Peach with some lavender in the art somewhere.
