Unisex fashion is all the rage, but will it be accepted into the mainstream?

Blurring the gender lines wasn't always as hip as it is today. Back in the 1930s and '40s, when Hollywood starlets such as Marlene Dietrich and Katharine Hepburn first pulled on wide-legged trousers and mannish button-down shirts, the look was considered scandalous and decidedly unfeminine.

Fast forward to the '90s, and androgyny officially became mainstream, thanks to the rise of feminism and pioneering designers such as Helmut Lang and Jil Sander.

In the first decade of the new millennium, girls dressing like boys became a recurring fashion trend, as women continued to "borrow" items from men's wardrobes, lending to the popularity of items such as "boyfriend jeans" and "boyfriend jackets".

At the opposite end of the spectrum, designers such as Hedi Slimane at Dior Homme redefined traditional notions of masculinity by creating a new silhouette for men consisting of slim-cut blazers and skinny trousers. Surprisingly, the jackets became a cult favourite among women who claimed that they fitted better.

Today, fashion is more interchangeable than ever, with men dressing in womenswear (see Kanye West in Céline) and vice versa. As such, a new category has emerged as many designers build entire brands based around the concept of unisex garments.

Unlike the androgynous look, which sees both sexes mix and match popular items from each other's wardrobes, unisex dressing doesn't discriminate, and eliminates gender norms.
