The outfit can be repaired with Enclave scientist outfit, lab technician outfits, scientist outfits, and Vault lab uniforms. The glasses can be repaired with a large variety of other glasses (see infobox).
The Lone Wanderer can acquire the outfit by reverse-pickpocketing Doctor Li. After activating Project Purity Doctor Li leaves the game, making it unobtainable (with the exception of console commands of course) if it hasn't already been retrieved.
Note: The unique glasses that were originally meant to go with this outfit were cut from the final version of the game and can only be obtained through console commands.
