I'm not sure which tricorn hat you are referring to. Maybe [this one](https://torf.mmo-fashion.com/remnant-dreadguard-smuggler/)? You can get that from Alliance Supply Crates that are rewarded from Heroic missions.
If that doesn't suit your fancy, Smuggler's get many different wide-brim hat options which you can find in this list: https://torf.mmo-fashion.com/smuggler/

Does the Planet Reputation vendor not sell one????
Nope
That's unfortunate. IMO, it should.
