待我长发及腰等我西装革履
[dài wŏ zhăng fā jí yāo dĕng wŏ xī zhuāng gé lǚ]
'When My Hair Reaches My Waistline and Until You Dress Formal' is a poetic wait-and-see approach toward future reunions, transformations, milestones, or commitments. This often refers romantically desiring mutual readiness before embarking on important life decisions together.
