Should i still have a quinceanera even if i dont get a crown?

i was originally ganna get a crown but my stupid parents(forgive me bcuz im very mad rite now) decided do have another baby n they r way to old to be having another baby btw n it might be a girl so that means if i have my party i wont be able to get a crown n my sister will so should i still have 1 i mean the whole reason i having the party is to get a crown n ill be the only girl in our family to not get a crown so should i have my quince or not?
