Help me pick a Jr. BM dress

My dress is an off-white/ivory and the bm's are wearing burgundy (first one)- which dress should I go with for fh's neice.

with the burgundy ones I am afraid she will look like she doesnt match the girls and with the ivory- the bridal shop will change the belt to a burgundy one that matches the bm's dresses exactly- but she may not match my dress & that may be off

thanks for your help!
