Navy hat from enemies, are there other navy cloths form drops?

[Pirate lord 227]

No definitive evidence, but i would say probably no. I have seen nobody with navy clothes on besides the hat. Who knows, maybe it is part of a disguise for a quest later *cough*Getting the recaptured black pearl back and defeating kraken with it by dressing up as navy and taking the lazy guards' shift while we turn a blind eye to the stealing pirates*cough*. If so, i seriously doubt all the pieces would be out quite yet, because there are probably other effects of the costume, like being unable to be attacked by navy while wearing it unless you attack first.
