How would you describe a behavior that is "unseemly"?

A behavior described as "unseemly" is one that is inappropriate or not in keeping with accepted standards of propriety or decency. This term often applies to actions or manners that may be considered unbecoming in social situations, implying a lack of good taste or decorum. Therefore, the term aligns perfectly with "unbecoming," reinforcing the notion that the behavior deviates from what is expected or deemed respectable.

The other choices do not accurately convey this meaning. "Completely acceptable" suggests an alignment with social norms, which is contrary to the idea of something being unseemly. "Highly praised" implies admiration or positive judgment, which would not apply to behavior that is frowned upon. "Conspicuously elegant" describes something that is notably refined or sophisticated, directly opposing the notion of something being deemed inappropriate or unsuitable.
