If this hat is too complicated for you, then you can just tie a piece of yellow fabric around your dolls head as a headband.Make a strap for the goggles/glasses by following the instructions for how to make the straps for the overalls, except in black material, and glue it onto the each end of the goggles/glasses.
Make a G symbol like this and glue or tape it onto your overall pocket and you are done!!!
