Answer:
A seasonal fashion statement named for the weather it's worn in.
We traveled the sea far and wide. At one time, two of my sailors were standing on opposite sides of the ship. One was looking west and the other one east. And at the same time, they could see each other clearly. How can that be possible?
I start in little but I end in full, you'll find me in half and complete.
They come to witness the night without being called, a sailor's guide and a poet's tears. They are lost to the sight each day without the hand of a thief.
I cannot be felt, seen or touched; Yet I can be found in everybody; My existence is always in debate; Yet there is a style of music named after me.
It is something you will never see again.
