Will the party be inside or outside?

I have decorated with all white, crystal/glass, silver, and gold, with lots of little candles, and it gave a very elegant and glamorous, but not Christmas-y, look. I got the idea from some web site; can't remember which. Anyway, it was just for decorating tables for a dinner party for about 18 people, but you could extrapolate. It was a challenge, because it was a birthday dinner for a dear friend who had recently been suddenly widowed just before a big birthday for which she'd had a big party planned (and of course cancelled), so we needed it to be nice and special without being too traditionally festive, KWIM? Anyway, I collected all the small glass or crystal and silver vases, candle holders, pitchers, jam jars, and so forth in the house -- even pretty or plain jars. You want lots. I put clusters of white mini roses in all of them and put plenty of white votive candles in each group. Then I wound around strands of garland made of sparkly stars. It all twinkled and reflected without using any lights. I used the same decorations for a dinner the day before a wedding, too.

You could do something like that, just stay away from too obviously Christmasy stuff; definitely no red or green. Maybe blue or black tablecloths? I used white. You can also rent a few potted trees and put tiny lights in them and put them around the perimeter of your space. Stay away from evergreens; think more tropical or something like ficus.

Happy birthday to your husband!
