Meaning of a sentence

The passage below is from Jane Eyre by C. Bronte

The matrons, meantime, offered vinaigrettes and wielded fans; and again and again reiterated the expression of their concern that their warning had not been taken in time; and the elder gentlemen laughed, and the younger urged their services on the agitated fair ones.

On what’s going on : there’s party going on in Rochester’s mansion when a fortune teller offers to give women before marriage a fortune. Then four misses, one alone and three together, go to have heard their fortune. So comes the quotes passage.

On this passage I cannot figure out the meaning of the word, ‘fair.’ Dictionary presented 15 adjective meanings for this word. However I can not pinpoint which is suitable for this passage. Honestly I can not figure out bold faced ‘the younger urged their services on the agitated fair ones’ altogether.

Thanks.
