Help?? Who stands where???

It doesn't matter so you could either choose which one you want next to you, flip a coin, or just arrange them by height

I agree with Amber; I would just arrange them by height unless they agreed on something different (and they're both okay with it).

I don't think it matters. I would have the one who will hold your bouquet during the ceremony stand closer to you.

I'd just do by height!

It doesn't matter. you pick who you want next to you. i only had 3 girls in my party, 2 matron of honors (sister and best friend of 12 years) and my step daughter was my bridesmaid. i had my step daughter stand next to me with my daughter (flower girl). it made for great pictures

I had my two college age sons stand with me. My younger was next to me and held my hubby's ring and my small bouquet when we did vows. My older one signed the wedding license! In all fairness they did not care where they stood, I am sure your girl don't care, either!
