You'll stand out in the Halloween crowd with this great costume.
Horns: Make the basic horns with knobby ends.

Ears: Cut two elongated tongue shapes from brown felt. Fold the flat edge in quarters, as shown. Use masking tape to secure the ears to the band.
Mane: Follow the instructions for the unicorn's mane, but extend the giraffe's brown felt fringe all the way up to the front of the hood.
Tail: Cut a square of felt into fringe. Glue it to the end of a felt rectangle, then roll it up into a tail. Tape it to the pants waistband.
Apply masking tape to the sweatsuit in a blocky giraffe-fur pattern.
