I found that for coats and jackets (I live in northern Indiana, near Lake Michigan, so I have a considerable amount of both) they are bulky and heavy.
This makes for quite an aggrevation when hanging them up.
My lazy solution, which I have now done for around 20 years, is to hang them over the backs of 4 chairs around a table in my room.
It actually works well, the items make the chairs more comfortable, and as there are four chairs I can organize them pretty well.
My unlined trench coats (like the ones on M*A*S*H*) are on one, my heavy lined field coat is on another, the rain suit on one, and my jackets are on the last one.
I just open the coats around the backs of the chairs.
If they get damp from the weather, this also helps them to dry quickly.
