/cgl/ - Cosplay & EGL

I'm not sure if this is really /cgl/ related, but I know goth lolita is a thing, so I figured it was my best shot.

I'll be going to one for a vampire event next month, and I have no clue what to wear. I only cosplay and I know almost nothing about lolita, much less if goth lolita or something similar would be accepted at a place like that.

If any seagulls have gone to a club/bar where the attire was strictly goth/historical, what did you wear? I hate how the tacky PVC corsets and things look, but I don't want to look too overdressed in a full bustle dress or something. Can anyone give some insight?

Also, if any of you have attended a vampire-specific event, what is the proper etiquette and protocol? I'm totally lost, and I don't want to make a fool out of myself.
