I have convinced my mom to try her hand at making my wedding dress

.. I would like to have a detachable half skirt but we are not finding clear tutorials online or images of the methods for attaching a skirt and making it look seamless. Does anyone have any images that can be shared so that we can get an idea of how it works? I know there are different ways including a snap, hook and eye, button etc but seeing how it works will be helpful.
