/cgl/ - Cosplay & EGL

So at Otakuthon I made my first real costume and it had some flaws. I was curious, for the necklace and the broach on the waist what could I make them out of? I was constantly hotgluing it back together because everytime I sat or a kid would hug me they were breaking. I made the necklace out of circle rings wrapped in aluminum foil then clay and baked sealed with modpodge. the broach was done with wire, hoops and AF, MP and clay. But the broach by the third day had at least 6 cracks and the necklace broke in half.

Also for the bow I did the tops [yes i know i did them the wrong way] as uhh- Styrofoam. Was there something better?

Lastly any suggestions for how to keep the hood on my head? It was constantly being pulled backwards and exposing my wigcap and unfort there are tons of pictures floating with me wigcap exposed and no one telling me. ugh.

Anyway, any crit/advice for my first costume would help.
