Now I'm on record (repeatedly) on the subject of just how lame a character Boba Fett actually is. Third worst in the entire Star Wars universe isn't hyperbole. That's actually where I think he ranks. Fett has one thing and one thing only going for him. He looks pretty cool (in a 70s sort of way).
So Amber Arden's costume (as photographed here by Estrada Photography) takes the one good thing about Fett and makes it massively cooler by combining it with a Disney Princess. Snow White to be specific.
Not only does she give the Mandalorean armor the correct color scheme, she's even put a bow on the helmet! Though since she's got a bow in her hair too that does seem a tad excessive.
Snowbafett is probably a better bounty hunter than Boba too.
