[If the Vulcan deemed it necessary, then a demonstration would have to suffice. But first, to answer Spock's question...]

Aye. Me clothes, of course.

[Thankfully, they weren't far away from where the hat had been, having arrived together, presumably.

There were his dark brown breeches and double-breasted waistcoat of the same color, along with the leather swash boots. His white shirt was there, as well, which was what he began putting on first. It finally felt much warmer than it had before, not to mention that there was an element of uneasiness before at the prospect of a man of his stature walking around with nothing but a pair of white cotton pants.

Now fully clothed, just like he had been before being sent to this world, Barbossa turned to face the Vulcan.]

A journey to this... 'Good Spirits' also sounds good, Mr. Spock. Me hopin' they happen to have rum.

[As for any future clothing he could get, Barbossa would make a later trip to this store at some point.]
