I might end up starting over myself so I can play the Nuka World good ending mod when it is finished. I think the part about the Vanilla Cleanroom suit is the color of the gloves. Will post again if i can find a picture of it when i get back to my pc it's just the closest alternative to what you're looking for that i'm aware of. the retexture itself and overall coloring of it does look pretty great imo, but yeah, that's understandable if it's not what you're looking for. The head/helmet/hood is probably the biggest, most noticeable difference between the Lima mod retexture and the picture you posted, so that might be a deal breaker for you.

unfortunately i'm in the process of reinstalling my game and all of my mods right now since i'm going to start a new playthrough, so i can't just load up my game to take a new screenshot atm.

I'll have a look to see if i can find any screens that i took of the retextured version from the Lima mod. Understandable, i just recently played through that mod so it came to mind and figured it might be worth mentioning. Is there a screenshot of this retexture I can view? I dislike the cleanroom suit no matter what texture it is. Personally, I preferred this because it's not a standalone hazmat suit but it's a lab coat with a hood. the retextured version of the suit from Lima looks great imo, and while it's not exactly what you're looking for, it's the closest that i've seen to the fo3 version The suit’s colors are also changeable with many of the options suiting the game’s base factions. Niero has made this Fallout 4 Armor mod with great textures that have believable weathering patterns such as dirt accumulating near seams. The vanilla cleanroom suit is one of the most hideous outfits in the game in my personal opinion, but i think it's just because beth used such awful textures for it. The main draw, though, are the looks this mod brings. Closest thing i've seen to the picture in your post is probably an Enclave retexture of the institute's cleanroom suit added by the mod Lima Detachment.
