Jewellery is an obvious one, but if want something a little different I really like the Disney personalized silver bookmarks. I found them on the
Disney store.co.uk site but for some reason I can't look at the .com version as it just refers me back to the UK site. They are available in Mickey and Tink versions:

There are also money clips available for the grooms men.
Photo frames are a lovely gesture and Disney has some loverly understated wooden frames that will fit into almost any home.
Mickey ears with the bridesmaid names stitched on, would also be fun, perhaps even with the word bridesmaid and/or the date of your wedding.
A Disney compact mirror of some sort or perhaps an umbrella? I'm quite partial to these two:

Disney also do some nice scarves in a whole variety of colours:

Another alternative would be to have some chocolates/flowers left in their room whilst they are at your wedding as a nice surprise for when they get back:

Sorry they're not particularly creative, I'm sure other brides will come along with far grander ideas but I hope these give you a little inspiration.
