Just buy a bag of disposables.. and most of u’re own makeup and let u’re MUA use some of hers/his for the contouring.
Bridal makeup, unlike theater makeup is fairly simple.. doesn’t require a lot of tools and puffs! 
Just make sure the mascara/eyelash curler/eye liner is u’res.
I buy all my supplies from here:
