How is this possible?

We tend to think that by sectioning off a store by sex that Unisex clothing is an impossible occurrence. 
Instead, Fashion today tells us that trends are constantly changing but Unisex is here to stay!
Commonly, you will find a similar version of a top for a man converted into that for a woman.
Not to say one is more feminine or more masculine than the other.
Since times have changed, so have the perspectives of appropriate  attire. 
Or shall we say "Trendy" attire.

You'll find women feel more comfort in the popular boyfriend top and men in a sleeveless tank. 
By the looks of it the idea is not far fetched that unconsciously both men and women share the same taste.
