I've done a "Return of the Jedi" Boba Fett costume, which is 501st qualified (BH-5247).
Since then I have created my own version of the Boba Fett costume. The whole idea is just that if I were to gallavant around the galaxy with the most notorious bounty hunter ever, this is my choice of outfit.
I have no idea what part is what or what it should.... I just thought it looked good. I don't have any knowledge about the Mandalorians or whatever, I don't even like most Mandalorian stuff.
IMO even Jango Fett was a Boba Fett tribute, nothing more (though I like the character).
Bucket was a 3 piece ABS vac vormed kit, Gauntlets were Fettpride's kit.
The rest was all made and manufactured by me, using PVc piping for plastic etc and a variety of textiles.
