The Shirtzie is an innovative combination of the traditional button-down shirt with a functional bottom snap closure for easy diaper changing (sizes 3-24 months). This 100% cotton shirt is expertly tailored from the finest woven cotton and is accented with premium shirting trim on the placket and cuffs. The collars are always lined with the softest cotton terry for that extra comfort. The toddler shirt (sizes 2T-4T) are available in the same styles as the Shirtzie but without the bottom snap closures. The Shirtzie and Toddler Shirt are perfect for the child that crawls hard and plays hard.
