I don't like them. However, if your friend gets them she really needs to research drs. A bad boob job makes people look deformed. A boob job done well can look okay. People need to consider their body type with the size they get. Some people look ridiculous when they get such large implants. I've never felt any so I can't give you my vote on that. Of course see them as very appropriate for cancer survivors and people who are dysfugured in some way.
I think there really good. Everyone says they look bad and fake but there will be a lot more people seeing your body with clothes on then with out.. At least I hope.. I don't think there good for people who already have big boobs but I am 16 and I barely have anything! Boob job is hopefully in MY future!!
