Yes. It is considered extremely rude to be bareheaded at any Jewish ceremony.
Jews males keep their heads covered at all times to show respect for G-d.
AnswerIt`s acceptable for Gentiles to wear a kippah (the Hebrew word that most Jews use). However, if you don`t feel comfortable wearing one, that`s fine as you`re not Jewish so Jewish tradition doesn`t apply to you.

At a wedding where it's obvious that most of the guests are wearing yarmulkas, doing so is a gesture of respect toward the venue, the couple, the occasion, and the Jewish guests. It wouldn't hurt. However, if you don`t feel comfortable wearing one, don`t feel that you have to.
