I think this should probably be either in the Sarlacc Pit or Other Star Wars characters sections rather than Boba's armour.
Anyway that aside, It looks to me more like it's simply an armoured Jedi. Look at it this way, if you fight armoured Mandalorians long enough, not to mention Sith troops and Sith Lords; with blaster bolts flying and sabers buzzing around your head you're probably going to work out pretty quick that your tan coloured pyjamas aren't doing much in regards to protecting you and opt for a nice set armoured over-alls instead.
