My five year old daughter has a friend who will be attending our next event with us. (Her mom is coming along.

) As they are close in size, I have extra to outfit her with- a chemise and/or undershirt, drawers and a corded petticoat, and a dress. But I am afraid that the petticoat will slip down without anything to attach it to. Should I have her wear the undershirt and add some buttons to the hem for the petticoat to button on? Or should I have her wear the chemise and make kind of suspenders to button the petticoat to? Or does either choice sound plausible?
