MAJOR UPDATE::  Adds an Armoured Vault 13 Jumpsuit to the game.  It has it's own mods, which are very good, imho. So good you don't really need to Add Ballistic to it, although you can, and it should still just count as "underwear" to the game, so you can wear it under some armours. I suggest The Chosen One, the combo looks totally OP imo. Working on another major update, to add a better model, but that's tomorrow's job.  I guess I mean "today's" job, it seems to be morning again.  Enjoy folks.
 <<V3 Update: No-one told me this mod was broken before a day or three ago, so I had no idea it's been bad for 6-10 months? . Also know a lot more about modding Fallout now, which helps. V3 Doesn't change the stats or anything, just a redo with new-er textures and I'm using Loose files in a zip, not a BA2 file now, as well, having issues with textures in the ba2 not applying(?) Should be all gtg now, but if there are any issues, PLEASE post a bug report asap, folks.
<<V2 Update News:>>

I went a little crazy learning about 3d modelling and editing meshes, and made some armor to go with the Jumpsuit. My inspiration is the Armored Vault Jumpsuit in FO1 + 2, passed down the family and modified until it gets discovered somewhere in the Commonwealth. I tried to design what I thought would be a good playthru armor, equip it and forget it besides an occasional upgrade. I know a lot of people like chest armor upgrades (I love BioComm,) but that's a choice you've gotta make, since I could NOT get it to work right, and I won't release a broken mod. Since IDK how to mess with questing or storytelling to add it to the game that way (yet) y'all just gonna have to imagine that part. It's available at a chem bench under utility, as is The Chosen One, a standalone armor piece. It's basically just a mashed together light leather left arm, chest armor, and right leg, but it just counts as chest and arm in-game. Has it's own stats and modifications, such as : Grav Harness, an enhanced falling damage reducer, and a Jestpack, for all your rocketeer needs. NB that the flames come outta your feet, but still work fine, so...  Has no other mods, as it's supposed to be a companion to the Vault13Suit, but as stated, it is standalone, if wanted.  NB that the Grav Harness doesn't increase fall distance or reduce limb damage much (if at all) so be careful!!! You can fall and take 2 damage and still break both your legs, happened in testing.

<Install/Update Info:> If you installed the previous version(s), uninstall, and clean your save (remove all copies of the item(s), save,  disable the mod using NMM (or whatever) load your game. Say yes to the content/mod warning, and save again.) then install the new version. Might not be totally necessary, but better safe than sorry.
And I had to package The Chosen One manually, the CK crapped out every time I asked it to create a ba2 with that mod, so if there are any issues, please file a bug report asap.
