你若长裙及身我必短裙相伴
[nĭ ruò zhăng qún jí shēn wŏ bì duăn qún xiāng bàn]
'If you wear a long dress reaching the ground I'll be there with my shorter skirt.' This represents companionship and harmony, expressing dedication: no matter what you choose, whether something more conservative (a floor-length gown) or unconventional, they will be there alongside you as well.
