I now have the normal, violence, and ultimate violence petticoats from Aurora so I wanted to talk a bit about them in case it can help others choose one for themselves. The ones I have are all 45cm, and I think I am just missing the super violence version. They all have a cloth layer inside all the organza as mentioned in the listing, so that provides some comfort to your legs when wearing them.
The normal is the one I recently bought, so I can't say about how it may do over a long period of time, but the other ones hold their shape and puff very well after months of wear.
The normal version gives dresses a nice amount of puff that is easy to move around in and sit in. Unsurprisingly, it's the most lightweight of the options, so it's great for casual use or traveling. It gives dresses enough of a silhouette to look like proper lolita dresses, but it may not puff them out enough to show details of dresses with more elaborate prints. It may also not be the best option if the dress is on the heavy side.
The violence version does give dresses more puff, but it may not be super noticeable in pictures compared to the normal version. I think it's more apparent when comparing them in person. I can definitely feel that it's heavier though, but not so much that it couldn't also be used as a casual and daily option. Before I got the normal version, I could still wear this one and drive without much issue. I think that if someone is new to lolita and wants something that gives them a good, defined silhouette but isn't sure how comfortable it would be, then this option will be a solid first choice.
The ultimate violence version is a good deal heavier than the others, but the amount of puff it gives to a dress is visibly more than the other options. I think it would be hard to travel with unless you're putting this one in a checked bag or if you have someone else driving you around. It definitely gives dresses an impressive amount of puff and looks nice with both light and heavy dresses. Since I don't have the super violence version, I can't really say if ultimate is a better deal than super, but I think it's funny to have a petticoat called ultimate violence.
