David’s Bridal Appt - bra & bridesmaids dresses

I have an appointment tomorrow with David’s Bridal for my two bridesmaids (17 year old future step-daughter and 9 year old daughter). I also need to order a bra for me, a long corset type bra. Should I take my dress with me to try on with a bra to make sure we get the right kind? I have never had good luck with just taking measurements and ordering from that for bras. My body doesn’t fit into the usual size for some reason.

I’m also a little worried that they aren’t going to let all three of us be there. Their safety instructions say this:

Limited Store Occupancy

We are limiting the number of scheduled appointments and customers in the stores. To ensure that we can accommodate you, we encourage you to make an appointment—but it’s not required. For the time being, we ask that you limit your guests to 2 at your appointment. We welcome you to invite additional guests virtually!

I am reading that to mean me and two others. Is that how y’all are reading it? I’ve tried calling multiple times but they aren’t answering the phone even though they are open. Any advice would be appreciated.
