There is no comparative form of "haughty," as it doesn't exist in English. To express varying degrees of arrogance, you could use words like:
* More arrogant/disdainful: This emphasizes the increasing level of arrogance and disdain.
* Slightly haughty/imperious: This indicates a milder form of arrogance.
* Extremely haughty/supercilious: This emphasizes the extreme nature of the arrogance.
