what do i do with my bridal party?

I’m not one to speak up and will 100% let people walk right over me because i’m weak and i just feel bad about everything. SO here’s the problem, what do i do if my bridal party expecr me to pay for their dress,makeup and hair? I haven’t said i am going too but they have said way before i asked them that it’s the brides job to pay. I’d absolutely love too but it’s going to cost me like 1-2k extra if i did. Thoughts on this?

UPDATE: i’ve only chosen the colour i’m

going to let them get their own dress but i’d love to be shown first because i don’t want anything too booby on them
