Your lost of clothing was more than likely due to the Inventory update, where pirates who didn't log on found that they had lost everything that they had. This was, however, temporary - as soon as they logged on, everything was back. Are you sure it wasn't just this bug?
In any case, it's very simple to get clothes and weaponry, as others have stated. Simply head to a boss (like Darkhart on the back of PDF) and chop away at him for a while. Even only an hour should get you some decent stuff. And, yes, basics are even able to reclaim some clothing.
I would also suggest contacting Disney on the matter. Ranting here won't do much, while telling Disney may get them to do something.
Best of luck! Happy pirating!
