Bridal Party organisation

Hi all.

I’m getting married later this year but idk the etiquette around the bridal party..

Do I pay for their dresses? I sort of want them to pick their own style according to a colour scheme.

Do hire a make up artist for us all or do I give people the option of doing their own?

I was planning on buying their bouquets and helping them choose dresses.

I was planning on letting them both choose a dress that they feel comfortable in with a specific colour scheme as their body types are on entirely different ends of the spectrum.
