I’m not sure if I’m being a bridezilla or not

We are having a child free wedding. The only two kids allowed at the wedding are the flower girls they’re my partner’s nieces. They’re lovely super well behaved and great kids.

Today my partner asked if the girls can wear white tuxedo jackets to the reception. Idk why it made me feel a pit in my stomach. They showed me the pic and it’s one of those white tuxedo jackets with the black lapel but my partner kind of jumped the gun and said yes without letting me think about it.

Tbh I wanted to be the only one in white at the reception, especially since my wedding dress is red not white because I’m Asian but at the end of the day they’re kids and I feel like I’m being unreasonable and a bridezilla so I almost feel like I can’t trust my own judgement right now

Another thing is one of the girls is my height or almost my height and I’m quite short, so it’s not even like little kids? She’s 12 but my height. Idk if I’m making any sense.
