While some themes for the Met Gala may be occasionally questionable, this is somewhat of a rarity and certainly not the norm. The theme of the Met Gala itself is not inherently distasteful. It is the job and challenge of the various designers to create ensembles that reflect the theme, while avoiding entrapping themselves in stereotypes or cliches.
The themes are also not chosen without thought for cultural or societal implications. For example, for the Heavenly Bodies theme, the Met Gala board worked first to gain the Vatican's approval for the theme. In addition to giving approval, the Vatican also donated upwards of forty artifacts for the Costume Institute's exhibition.
