From her blog:
There is a wide range of opinions on what constitutes good judgment with regards to how women dress themselves and how much they should or should not cover up. Any time a woman is told to cover up or told to undress, I see that as an attack on her person. Telling women to cover up and telling women to strip down are frequently used tactics for oppressing women. There are both practical and philosophical reasons why no one other than the woman herself should decide how covered or uncovered to be. It is easier for onlookers to avert their eyes than it is for a woman to dress in a way that makes her feel uncomfortable.This is true of how much skin we show in dress and how much skin we show when breastfeeding.
As she writes in the video, "Beauty may be in the eye of the beholder, but when it comes to dressing and breastfeeding, appropriateness should be decided by the woman."
