/cgl/ - Cosplay & EGL

Thinking about straightening one of my curly lolita wigs
The problem I have with this wig is that it's way too voluminous on top and makes my head look bulb shaped. It's almost hourglass shaped for a wig, if that makes any sense.
I'm worried straightening it will just make it worse - it's really hard to style for my long face shape. But I want a long brown wig and already have this wig I don't know what to do with so maybe it's a good idea? Like straightening it might take away the weird middle indent it has before forming curls.
Pic wig is kind of similar. I know there is a wig help thread, but it's all cosplay and this is a more lolita/jfashion related question. I know how to straighten it I just don't know if I should.
