For an unexpectedly delicate table setting, why not pile on the glass and crystal? After setting this, I realized that I was sorely in need of glass plates! Luckily, they're easy to find and extremely cheap: Target, for instance, has a basic set of 12 for 24.99.
The look doesn't need to be extremely costly, either. Use whatever good crystal you have, pair it with cheaper glass where you need to fill in, and keep the silverware simple.
Oh, and for the love of god, no plastic.
