This is less of a tutorial and more of a guide to create your own cage petti for lolita fashion. It will aid you in making one exactly the size you want for yourself, but keep in mind, it will require a bit of math as all sewing does. You can easily change the shape by swapping out the type of petti you layer on top (A-line vs Bell). This is by no means the only way to make a cage petti or the correct way. This is simply the way I made mine along with my friend Frilly Dragoness!
