I had asked my sister to be a bridesmaid which she of course acceptable. She had recently gotten a tattoo and I just asked that she not get anymore that were visible because our wedding is extremely formal. I told her I was totally fine with her getting tattoos that were not visible. She promised she wouldn't. She went and got a tattoo on her forearm. I also asked all my girls to wear silver shoes either heels or flats she wants to wear sneakers which I said no to, but she is complaining because she does not want to be taller than her date. Her date also has a seven year old son. We are not allowing any children aside from the ring bearer and flower girls. My sister says already made the comment that no one can watch the son. I do not know what to do.
