The concept of gender-neutrality isn't a foreign one when it comes to fashion.
For example, London's department store Selfridges' retail space Agender, which aims to provide its customers with the opportunity to shop without any preconcieved notions about fashion for different sexes is way ahead in that department. And now, Amercian Apparel's got underwear that's designed to work equally well for both men and women! So, couples sharing undies is on it's way to being totally normal!
While for men, undies are mostly about the comfort favor, with women, appearances are often everything. What's really cool these undies are that defy the norm for women and have created something that puts sees on par with each. We lOVE!
