So if I got the Federation and I modified it like they show at Indygear, I could still send it in if my head grew some more and not have to pay anything (maybe shipping)? I may go with that. At fifty bucks it does look like a steal, given the other prices for hats. And while we're on the subject of hats, would you recommend getting a Herbert Johnson once I have the spare cash, or just stick to the Federation?
Besides the bag and hat I would probably just get a whip, guns, and belt with holster(s) and whip holder. I think the things that would get the most use out of them would be the hat and bag, so I'd probably start with them first. I'm definitely going to wait on the jacket, shirt, and pants until I'm sure I'm done growing (I'm on the large side, not as in fat, but just flat out built large, so how big I'm going to grow is a bit unpredictable), same with the shoes if I want to get the Aldens, but as Ren said, any boots should do for now.
