Best black overcoat for winter?

[MegaChopped]

Where would you buy a black winter overcoat for winter? Also what kind of cut/length (knee or mid-thigh) would you recommend? Obviously 100% wool so it will last. Suitsupply seemed to have a decent selection. Budget is like 600

Used selection here wasn't great and should probably buy a longer cuff model since I'm 6'5.

They don't seem to have 100% wool ones. All have some plastic shit in it
