It's a product not the quality. If a girl sees another girl wear the "Love Pink" yoga pants and likes it, they will wear it and so on. It's like a domino effect of peer pressure. Have you ever noticed how one clique of girls happen to dress and act the same. I'm not very educated on the subject, but I know for a fact it is not for breast cancer awareness.
The brand has nothing to do with breast cancer. It's Victoria Secret's brand. During the month of October (Breast Cancer Awareness Month), they have a support clothing line, but it's not the "Pink" or "Love Pink." Pink is just the name, but it is not referring to the color pink. It is referring to vagina, as pink is another word for it. It's named that because it's only for women.
