Joseph and Mary Costume

i am 7 months pregnant and was trying to find a costume that would fit my belly into character so what better way to show apperication to the virgin mary. my boyfriend plays the roll of joseph and i am the virgin mary herself. we bought his costume and i made mine from head to toe. please understand we both did not pick this costume to disrespect any relgious beliefs, we have already gotten disturbed looks for what we see in a different light, we both are just dressing up how we think times would of been back then. thank you.
