Today I just picked up a lovely "hybrid" formal jacket from RL Purple Label, which has a second smaller pocket just above the main one on the right side. Now I've seen some jackets and also overcoats with this, but have no clue to what it's called, or it's function (if there is/was one)? It seems to me that maybe it is an out-dated feature that some are bringing back? There are also some other strange things about the jacket. It is a three button with the most upper part of the collar being satin, though it is shaped like a tab with a button hole on the left side (so that you could stand the small collar up and button it across to the other side somewhat like a Nehru jacket, though it is more for detail than actual function) It also has satin that folds up at the cuffs about an inch, and curve off into a split. Finally it is also side vented. I feel it looks good enough to wear as a formal jacket (but if I'm mistaken it would help to let me know), yet would like to have more info on those mentioned details; history, names, and what not. Whatever any of you can provide is appreciated, thanks.
