I agree with the uniform part. If i remember correctly Yamamoto once scolded several of the captains for losing their cloaks or whatever he called them. They may have seemed like a joke at the time, but i'm betting Kubo did it intentionally.

Also odd thought. Maybe they got their measurements because they are becoming captains....
