Answer:
Neither your dress nor your look impresses me much.
Explanation:
Sentence agreement occurs when the a singular subject matches with a singular verb, and when a plural subject agrees with a plural verb.
<u>When singular subjects are linked by the words neither,</u><em><u> either and nor</u></em><u>, then the verb is also singular. In this case, both </u><em><u>your dress and </u></em><u>your </u><em><u>look are </u></em><u>singular subjects, so the verb takes the singular form as well.</u>
Similarly, when plural subjects are connected by the same words, the verb must also be plural. However, when the subjects linked consist of a singular one and a plural one, the verb form agrees in number with the nearest noun.
