I've never seen anyone look as good in a Vault suit as the actors in the Fallout show. The licensed Vault-Tec jumpsuits you can get from costume stores are spandex disasters, but even more expensive Vault suits aimed at cosplayers look a bit pajama-like. The show's jumpsuits, however, are form-fitting without being superhero-tight, and don't seem to limit movement whatsoever—they look comfy, but also cool, or at least as cool as a blue and yellow jumpsuit that designates you as a sheltered nerd can look.
Well, there's a reason. Vault 33's main sartorial advantage was of course having a team of expert costumers on hand to custom make their outfits, but those retro sci-fi tailors also had a secret weapon: hard-to-get Italian fabric.
