I think it is important to have at least two petticoats. Bell petticoats and a-line petticoats each create a different shape, so it is good to have one of each. Of course, you may need multiple petticoats of each type depending on the length of the skirts and dresses you wear. If you have a lot of different lengths, then you will need additional petticoats.
A bell petticoat has sides that are curved smoothly down from the waist, and will give a dress a full cupcake look. An a-line petticoat has sides that flare out from the waist similar to the letter "A".
