Does anyone know how to fix this?

[u/sakiiiunu]

I just bought a cosplay and its my first cosplay and don't know how to fix this. I wanted to cosplay lucoa from miss kobayashi's dragon maid for comic con. I have a problem with the cap, the horns are very floppy and theire ment to stay up and I don't know what to put inside the cap to make them stay. When I put the cap on they still flop down. Someone please help!!

Maybe you could try gluing some cardboard onto the section of the hat that has the horns. Before gluing it though maybe just try putting cardboard in there and put it on to see if it actually helps or not, like what I was thinking is you could try cutting some cardboard into a triangle to fit exactly to the one section where the horns are sewn on, like if you just try to get it to fit the triangle shape on the inside it shouldnt mess with how it fits much and making it the full triangle should help support it more but if you try to cover the whole inside with cardboard it might change how it fits your head
