These would depend on your budget and acceptance

i bought some china made ceramic white plates. not purely white and some uneven surface. but it cost me just RM5 each

I also bought some good qualities wan from Parkson. (but discounted) those range from RM30 for a 12" plate to RM90 for a extra large 20" plate. I bought it with 70% discount.

Note to consider when buying white plates, they might stain easily. I rested my plate on a steel (which i didnt know it will rust) and ended up with extra "design" on my plate. other than that, sauces and stains also might harm your plates.

as for cutlery, its best to get some good set. you dont need more than your usual personal usage.

for parties, just get those plastic cutlery and paper plates. that's how i mange my plates and cutlery. no point keeping so much set. small house only
