Who is Solange (007 in New York) from Octopussy and what is their importance?

Solange (the reader only knows her first name) is James Bond's date for the evening. She works at the Indoor Games Department at Abercrombie's. The reader knows nothing about her except that Bond is confident he will get a date with her. From the intimate details his reminiscences divulge, a long-term relationship is implied. He recalls that every time she and he have made love she retires to the bathroom for a long quarter of an hour after which he can not kiss her because she has gargled with TCP.
