zombie 1st birthday??

Love
So question of the day would be... is a zombie party a good idea for a Babies 1st birthday? Everyone always has such cute parties for their kids first birthday and I wanted to go a different way. I just don't know how other people will see it. I don't wana be looked down upon or be looked at as a bad mom for the topic I chose. Any suggestions on if I should do it or not..
