穿着婚纱参加你和她的婚礼
[chuān zhe hūn shā cān jiā nĭ hé tā de hūn lĭ]
'Attending your wedding with her in bridal gown' expresses a bittersweet or self-sarcastic emotion where someone might participate in loved one’s marriage even when that role was hoped for oneself previously. Reflects acceptance and grace.
