Hmm, while I'm here, let me make an observation.
While looking up Japanese clothing, it seems (to me) that Oda is attempting a double entendre with Jimbei's name. Apparently a style of clothing seems to work with the name as well, which sort of looks like what Jimbei wears.
If this isn't the case, I'd like someone to tell me what style clothing he's wearing. Call it curiosity.
No you're 100% right.
