Sammie, I did a few searches and found these. Not sure which you'd want to go with, but I searched 'frock coat' and 'ringleader', but then ended up on 'redcoat', 'British Navy', and 'Hamilton' as search terms for patterns. Nothing's quite an exact fit, but I feel like that will get you closer as you look around!
This really looks close to the Royal Navy uniform coat, but I'm not all that historically versed, this is just where google led me, lol.
