Hi, I wouldn't say its "tacky" but it may be too adult? It would be nice if they had a choice if they want them or not. If they get pierced ears when they're older then that will be something exciting for them instead of being forced into it when they were younger. I have to say, my mum pierced my ears when I was one years old. I never had a say and I think its better if you just let your girls decide for themselves. It could be something nice for them to look forward to on their 12th birthday.
