"the full uniform of the New Woman"

The New Woman was a new ideal of femininity that emerged in the latter half of the 19th century.  The New Woman was independent and independent-minded, would often pursue a profession (and more professions were open to her than her predecessors) and not hold a successful marriage as her sole ambition.  She was more likely to engage in activites still frowned upon as unladylike, such as smoking or riding a bicycle.
