The Aspiring Knight's Vest has long been one of my fav chest pieces in the game, sadly it cannot be dyed and is restricted to jedi knights/smugglers. I'd love see something based off of it, even with some subtle changes it could be a nice addition to a future pack or the market itself.
Possible changes: a hood up version, a hood down version, one without shoulder pad/straps... one without the skirting around the waist would be nice as well.
