Tiered plate holders for tea party (Magnolia)

Greetings! I'm looking for two- or three-tiered plate holders for a tea party baby shower my daughter is throwing for her sister. Round wire racks work well -- I have round plates. I'd welcome square or rectangular ones if you had plates to go with. I would also be delighted with the kind that have a metal rod going through the plates. A few examples attached. Thank you!
