I only wear silver/white gold/platinum jewelry so I never even think to match with the hardware on my bags! I have bags with silver and bags with gold, doesn't matter to me so much on a bag. I'm not really into the matchy matchy thing, my wallets, makeup cases, wristlets, etc don't have to match my bag. I love tons of colors and patterns!

I don't...my wedding jewelry is yellow gold, other is white or silver or platinum, and I like to mix it up. On my bags, however, I like the hardware to match for my accessories and whatever is on the bag. It's not a dealbreaker, but I do prefer it that way.
No, I love to mix it up. My wedding rings are a mix of white and yellow gold, and so is my favorite ring on my right hand which is a designer piece.
I always mix my other jewelry also.
Actually if you look at the recent designer jewelry, a lot of it is mixed metals. I just bought earrings by Mark Jacobs that are gold, rose gold and silver.
