pertaining to pea coats

I was studying the difference between p coats and trench coats which took my attention in wearing clothes. The slim fit p coats or pilot cloth is matched with slim fit trousers and with canvas shoes or long pointed formal shoes.
The pea coats are little shorter when compared with trench coats. The former does not usually comes with belts and the presence of double lining buttons confirm them with the later one.  There are various types of tench coats with different colors, the standard ones will be khaki and black. The pea coats are worn with a scarf to get the continental look.

Following are some of the Trench coats which vary with the former ones.
