SWR- Dresses for sizes 16 +

Hello Ladies.
I was hoping someone could please help me....I am trying to help out my aunt and she is looking for places that would carry dresses in a size 16+ for my cousin for her batmitzvah. As you probably guessed she's a very large girl and rather then her get upset looking for a dress in her size and them notcarry it I thought Id look into who has plus sizes in the stores.
I think they usually look for the princess, sweet 16, prom type dress. Thanks so much for your help.!
Just a sample :

Sugarplum has all sizes and you can try them on. Ann was very nice and helpful (some of them are a little snotty)
