Nice Bridesmaids gift for the over-40 (more mature) bridesmaids?

I am going to provide robes, but I don't really consider that a gift. Any suggestions (under $100) for my bridesmaids? They are all 40+ in age and upper-middle-class+, so it needs to be something nice and not just a trinket. I thought about a massage gift certificate, but then thought maybe it should be a physical gift like a bracelet (which I can't find any nice ones for under $100.) I contacted my sales girl with Neiman Marcus, but did not love anything she came back with. Would love it to be a good brand, but the Tory Burch bracelets are all a bit pricey. Anything great from Kate Spade (which isn't my normal style) or another trendy designer? Any great suggestions?
