Not really. You can get a duster, but it just looks like the Sheriff Duster in FO3
There's a trenchcoat in the GECK, but I think it's unplayable (it shows up on a corpse in Beyond the Beef). Both the Sheriff's duster and regulator duster are back, as is the enclave officer uniform, but all appear just once.
The NCR desert ranger looks pretty similar I think with added armour coolness
There's also The U.S Army General Outfit wich is unfortunately only available in the Lonesome Road D.L.C. But it looks exactly like General Chases Overcoat and Colonel Autamn's However it is been radiated so the colour of the Overcoat is brown/green.
