Yes, she's wearing a FNV mod/armor.

About this image

I covered up Silver's *ahem* modesty with a really-awkwardly huge looking MS Paint heart. I ported Nida Schuetlich outfit for Type3 over to FO3, it was a funny story: I took it from a wardrobe I put in her house that I didn't flag as hers. Then she comes over to talk to me about Moriarty in dialogue and after I choose the wrong dialogue option, she attacks me. After she dies, her wasteland outfit turns into the outfits I just took from the custom wardrobe! Wondering what the hell was going on, I looted her body to find that she had taken all the outfits from me right before going into dialogue with me.

It looks good on her, even if Silver is a corpse now. So I decided to share with you guys, while I refine my mods. I have four pieces, the suit, the two gloves and the underwear.
