Shopping Does petit soiree re-release doll heads?

Not sure about petit soirée in specific, but most companies do re-release sculpts given enough time, the timeline can be anywhere from 6 months to 2 years on average though. So waiting on that can be a gamble and it depends on how long you’re willing to wait. The other option is hoping that places like new clover singing ordered extra which can mean that the doll will show up on their eBay and to get notified about it you’ll have to follow their Instagram.
It might be more worth your time to put up a want to buy for the doll, I think petit soirée pop up on the second hand market place from time to time but it’ll be a couple months before anyone is selling a Caesar since the pre-order just concluded
