If you're on PC and not opposed to modding, this is the mod I installed. Why can't I apply it to an outfit that I find aesthetically pleasing? I can already apply it to one of these outfits and get the maximum possible benefits of having the ballistic weave under my armor. Like I said, there really is no issue with being overpowered by being able to apply it to everything. Here's a full (I think) list of under-armor clothing that leaves ALL armor slots open and can get the ballistic weave. It bothered me enough that I added a mod to open up basically all clothing items to ballistic weave.
I'm not going to have some kind of 'advantage' by wearing an armored BOS Uniform rather than armored fatigues. I can wear the fatigues under my combat armor and have the extra 110 damage resistance from the ballistic weave, but I can't wear an outfit under my combat armor that I actually like the look of and get the same benefits? Like I said.the only difference here is aesthetic. What makes it even worse is that for some reason you can only apply ballistic weave to a few under-armor garments. Personally I prefer the Vault Suit and the BOS Officer's Uniform under my combat armor anyway but I'd love it if the fatigues didn't make me look bloated.
