A Wedding Gift...in progress

My beautiful niece is getting married in a couple of months.  I haven't come up with any ideas of what do to.  Generally I would make a quilt for her, but since my mom has gotten back into quilting, she is making her one.  So now I'm left with the what to do.  Just buy something from her registry? Make something else, but what?  She is a simple elegant young lady.  Has wonderful taste and style and I would like something that would reflect that her very classy side.  I need some great ideas.
