Our WP includes my 2 sisters; FI 1 sister; and FI 1 brother as his only groomsmen. We decided to do only siblings. Our ceremony is outdoors, non-religious. Would it be odd if FI sister stands on HIS side, behind him, while we recite our vows? So me & my 2 sisters behind me; then him and his sister & his brother behind him? Or should we keep the girls all on one side? I suppose its tradition to keep all the girls together... but I don't really care about traditions! Help!
