I don't have the character to test but it doesn't look undoable, Voluptuous and Pear Figure is included in the clothes, as well as adjustment morphs to loosen the clothes a bit.

If all else fails I recommend Morphing Clothes by Dimension3D in the marketplace here - it will take custom morphs and add them to the clothes. Its not always successful but I don't see a problem with this figure.
