I've just enjoyed wearing my 9.1 scale Optimus Prime toy costume at the 2017 Calgary Comic Expo, this year with silver onesy & energon axe: http://i1276.photobucket.com/albums/...psseagfkft.jpg
Other than the apparent differences I also changed how the upper arms tether to the body and added 2 cooling fans, as it was apparent I'd be warmer wearing the silver body suit.
What might you change to this cosplay for its next use? I could wear it to Otafest on July 1st in Calgary if I wanted to, though travelling on Canada Day isn't my first pick. =)
