Beautiful Corpse Coffin Pocketses
It's not often one can say so, but the eighteenth-century really got something right: pockets.
Historically, women not only had pockets, but they had pockets that could actually carry their belongings. A separate garment unto themselves, eighteenth-century pockets would often be beautifully embroidered, and were worn close to the body and tied at the waist; all other layers would then have a side slash to allow the wearer to retrieve her necessaries in a flash. 
Having seen the light as a long-time historical costumer, I bring to pinup a pocket capable of carrying a full-sized wallet, keys, phones, and even large paperback books.  The design is not only spacious, but because it is a separate garment the weight of things-one-carries won't awkwardly pull a hem, or weigh down an otherwise perfect twirl.
All Vicious Poodle skirts feature side slits to allow access to pockets, and a single set can be swapped between outfits.
There are no rules for wearing your pockets. While it is recommended you wear them over your petticoats and under your skirt, they are stylish enough to wear on top, and certainly don't have to be paired with a skirt at all.
