How to build a long woolen coat with eight sleeves?
It can be worn with a tight white coat, and it will leak a little when you put on the coat. It looks good.
If your coat is thin, wear jeans and booties (because booties look so long and so high), so as to look thin and tall as a whole. If the coat is casual or heavy, wear a long sweater under it, with soles and high-heeled boots underneath.
