Speaking as someone not fond of her own body image, I certainly do understand how soul destroying it can be for girls who are unhappy with parts of themselves and the obession to look a certain way but the reality it unless you are majorly deformed, the problem is in your head. People who comment on other people's appearance usually are covering for their own issues so it's really not worth listening to them, even if it's someone you are close to in which case they are certainly not good for you.
I always think it's funny that guys go on about looking at large breasts yet also talk about how fake ones feel gross. Women can't win sometimes.
I'm not saying it's guys how put the pressure on, in fact women are far worse in my experience.
