Then came the forties!!
This was the era where women were able to start doing more. They wanted to be seen as more independant and able to fend for themselves. They started wearing what was considered men's attire and the makeup transformed.
Darker colours were used (browns) and the angry snare lip was introduced. The ticked eyebrow was beginning to take shape (at its prime in the 50's) and thicker eyeliner was also used.
