Junior Bridesmaid Dresses?

Good question. I definitely see that you’re in a bit of a predicament, but first, kudos that you’re considering having her in your wedding! It would be a moment she’d cherish forever if you two are close.

How old is your little sister? What do you ”too young” for a bridesmaid?
My FH’s little sister will more than likely be in ours. We’re still deciding, because we have several siblings... all varying levels of “closeness” to us. (Long story)
Her dress will be a “junior bridesmaid” dress that’s knee-length from David’s bridal. The color will match my other bridesmaids.

I’m not a fan of anyone wearing white other than the bride - even the flower girl.

View Quoted Comment She's 12, and my bridesmaid dresses are a deep v, so I don't feel comfortable having her wear that. I like the idea of a knee length dress of the same color that is age-appropriate. Thanks!

Maybe she can match the color of the BM dresses, but have her own cut. Does the place where you got your BM dresses have a Jrs line? As for who pays, traditionally in the US it is the BM or the parents of the FG/jrBM who would pay, but it is best to not assume and talk to your parents about what they would feel comfortable with. And as for what she can do, I had my JrBMs walk in front of the procession just like the regular BMs, holding smaller versions of the BM bouquets.
