Your sister will get married soon. What gift should I give her as a sister?

My sister and I got married in the same month, but I held the wedding in May and June. My elder sister's wedding is in May. I want to give her a gift because he wants to give me one, so I joked that it is offset, but it is definitely impossible as an elder sister, so I not only gave her a big red envelope, but also customized a bouquet and a pair of bridal shoes for her. After all, it's my sister. I hope she is happy.
