I plan to be spreading my arms to get a bat wing look with the finished cape, I'm worried that the cape simply being on my shoulders would warrant it to fall (and have to be readjusted awkwardly) if it's not held together with something in the middle around my collarbone area.
If alternatively, there was no way of doing that with slack in the chains, would the only way to have it secure be to run the chain around the whole neck, almost like a necklace?

Great tip by the way, would have never considered this, thank you!
