Shirts for four grandchildren

I picked out this extra-special version of the birthday shirt for my oldest grandchild whose birthday falls in September after the spring and summer birthdays of her sister and cousins. She loves that it’s black and she really loves the rainbow letters. Very happy to have found Not So Basic Birthday.
