BM gift help!

Hi girls! I'm getting ready for my upcoming wedding but I need to finish my bridesmaids gifts. So far I each got them a silk/satin robe with their monogram embroidered. I also got them each a Tiffany's Necklace. The necklace alone was a lot of money but I didn't want to get them all nonsense gifts that they will never use. However, I would like to get them something a little extra. Any ideas?

I also need help with an extra gift for my maid of honor and matron of honor. Thanks!
