I think make up is sexist, it demeans women to have to look 'like that'.
I did hear the idea that 'not-pretty' women get a more level playing field because of make up, and it is too bad looks help in this superficial world, but its still not worth it.
Make-up can be used as an excuse too:
To wear make up while overweight, in hopes of being attractive, is kinda sick - the time spent in front of a mirror could be used to walk the block 5 times and be truly attractive [to themselves].
I hope women can get off this ride and decide that life is amazing and all of us are too, with so much to offer how can we be fixated on what we look like? Stop comparing, stop competing, and just look at your wonderous self!!
