I think it's a pretty bracelet. Very feminine...I don't know why things that are considered "girly" get deemed as young. Even though we age physically, it doesn't mean we aren't entitled to cute & feminine things!
I think the bow bracelet is very feminine, as is the necklace. My only concern with the bracelet would be the bow is weighted, hence it would hang down and perhaps more likely to get banged around and lose a stone. But I would definitely wear both!
