does the Braintree store have a personal shopper person who helps you find the right clothing for your body? If so, how do I get in touch with that person to make an appointment?

Pretty much you can find an associate on the floor and ask them for help.

You can call the store directly they can help you out with that question

Call the store.

The best way to figure out that is too call the location directly. They will give you more info.
