White Lies

People often meke white lies. They make white lies to make other people happy or not upset with what we think. For example if one of our friends wore a dress which we think it is really ugly. But our friend is really proud in wearing that dress. She or he ask us if she look ok. Of course we don't want to hurt them. So we made a white lie to make them happy by saying "Wow...You look great on that". So, is making white lies is something wrong?
