Anyway, in this hunt, using the lists provided at The Vault, there is the Vault 101 Children's Jumpsuit. How can I collect this as an adult player, seeing as it goes away after you turn into a teenager, and there don't seem to be any kids in Vault 101 upon your return?
Note: I'm on an XBox 360, so anything involving the console won't work for me. However, for the sake of completeness, whoever gets here first with the console commands to do it for PC users, go for it. I just won't upvote (but I'm sure others will).
