Help! I am having a rare girlie moment and can’t decide

I have narrowed down my bridesmaids dresses down to these two but cannot decide on which one to go with. Both are beautiful but I completely need some help because half of my girls like the shorter one (who can blame them since we are having our ceremony outside in the middle of July) and the other half like the full length dress (which are very elegant as well and give that more classy look)
