Hi Jellyfield, since you brought up about bringing straws for drinking, you may want to ask your bridal whether drinks like mineral waters are provided.
And also an optional item if you are considering, if you want any cleavage or safe protection against accidentally 'lobang' if wearing low cut gowns while taking shots outdoor, probably can consider bringing a nude bra.
As for the slippers/flats, please remember to bring your heeled shoes for your gowns.
And ask your make-up artist to remember to give u face sponge and face powder for touch-up also... , just in case that she forgets or miss that out.
