Nuka World Clothing and Items
If the content in the Nuka World DLC isn't enough, take a look at this excellent Nuka World related mod from developer ShroudLegacy.
The Nuka World Clothing and Items mod adds a number of Nuka World items including shirts, beds, flags, coffee mugs, and even a set of bath robes.
There's also a brand new Nuka Mystery Flavor which will hum the Nuka World amusement park's theme song as you drink it.
If you're obsessed with Fallout 4's Nuka World and/or the Nuka-Cola Corporation, this mod will be of interest to you.
