In 1939 the young Christian Lamb felt she had to "do her bit" for the war effort. Her comfortable life was about to be turned upside down. With a Naval background, the Women's Royal Naval Service (WRNS) was the obvious choice, besides it had by far the most attractive uniform--topped by the splendid tricorne hat. On joining as a lowly Wren rating she found that this crowning glory was not for her but strictly for officers only. It was to be the first of many nasty surprises. In I Only Joined For The Hat the author wittily describes how class and snobbery had no place in a world of girls from all social backgrounds, suddenly plunged into life together. From scrubbing floors and squad drill to coding and catering, Christian peppers her pages with amusing observations.
