Iam a fellow plus size girl!!
Iam a size 22 in my dress...and this is the dress I have bought.
You definately have to try them on.. I chose many gowns online before going in.. and NONE of them looked good. Then I tried this one... not one I would choose off the hanger..but put it on and felt like a princess!
Good luck... i think the dress you chose is sooo pretty! Have ya tried it on?
