Super cute t-shirt alert! This has to be one of my favorite birthday shirts for boys. The front of the shirt has a skull and crossbones with the caption ‘Warning! It’s my birthday!*’ and the back says ‘*I can do anything I want!’. Pretty much sums up the birthday boy’s big day. This navy t-shirt is 100% cotton and has a tagless neck for added comfort.
