X-post: Flower girl dress

My flower girl was going to wear her communion dress but we just realized it probably won't fit her in a few months. So, now I'm wondering what color dress/accent to get. My dress is very light ivory and the bridesmaids are wearing platinum (dark silver) with purple (BMs) and pink (MOH) accent colors. I saw some really cute silver flower girls dresses and also some really pretty ivory ones. Would you do the silver or ivory? And would you do the sash for the dress in silver (with an ivory dress) or pink or purple (with either color dress?

Here are some ideas of what I'm talking about
