I'm not the person to ask about tableware clutter -- I own seven sets of dishes. I have four sets of everyday dishes (they vary in plate size, color and style), my wedding china, my grandmother's wedding china, and a set of Christmas china. I enjoy setting a lovely table. I enjoy choosing the dishes that will enhance tonight's dinner rather than simply allow it to be eaten. I like using my heavy, bright Fiestaware for a bowl of chili, or the rim soup dishes from my Pfaltzgraff for a pasta dish.
In contrast, I have only two sets of glassware -- simple everyday glasses and a set of red goblets that look great with the Christmas china. And I have only one set of flatware.
While you may consider this clutter, I am 100% unrepentant about my hoard of dishes. I use them, and I enjoy them. That's the line in the sand: If you have a lot of a certain item, but you're using it, it's not clutter. On the other hand, the most practical items -- if you never use them -- are clutter. For example, I have about 8 coffee mugs. They are NEVER used.
I agree that clothing is probably my biggest clutter-item (and when my kids were small enough to outgrow their stuff, it was worse). I think I buy fewer items of clothing than most people, but every couple years it seems that my closet has become too full -- again. People give you clothing as gifts, you pick up a tee-shirt here and there -- after a while, it adds up. And I find it difficult sometimes to say, "Yes, this is a nice dress, and it fits, but I haven't worn it in a while. Time to go to Goodwill." It seems wasteful since you might want to wear it again later.
I have a system that works well for clothing -- and you could do it with other things: I put unneeded clothing into a box, and I put it on the top shelf of my closet -- marked with today's date. In one year, if I haven't wanted an item in that box, I take it to Good will without opening the box. That way I am not tempted to talk myself into wanting the item back.
