To tell if your dress has padding and boning, go to the item page and check the notes under "Product Details." If the dress has padding or boning or both, it will list it here. if the dress has neither, it won't be listed at all.
For example, we can see that the Dakota has both padding and boning: 
But the Calla only has padding: 
If you are searching for a style and want to make sure it has padding or boning, both, or neither, we do have some helpful filters on our dress pages that allows you to filter by padding and boning called "Padding" and "Boning." The filters are the last two on the dress pages, on the left side.
If the dress you get has padding and boning and you would rather have them removed, that's a super easy job for a seamstress or for yourself if you have experience with sewing. You would just flip the dress inside out between the two innermost layers of the skirt to expose the padding and boing. With just a few snips, you'll be able to remove them easily.
If you plan to wear a bra with your dress and it comes with padding and/or boning, you may want to have that removed to allow more room and a better fit for your bra.
