Although first appearing in the late 19th century and worn by sailors, the jacket has retained the hallmarks and characteristics of its original design so that it has become a classic. Originally designed by Navy men to endure the harsh, cold temperatures that many of the men faced on the seas, they have become a classic.
Pea coats usually navy blue in color are characterized by broad lapels, double-breasted fronts, often large wooden or metal buttons, and vertical or slash pockets and the heavy worsted wools they are constructed from.
I find Navy surplus jackets to be the best and have had the same one for years, alternating buttons, between the original and gold for a more dressy look. I love the original buttons with the recessed anchors. Of course I always (85% of the time) stick to the classic navy blue, however I think other colours work quite well such as beige or grey.
