Simplicity2917 Dress and Tunic Sewing Pattern for Women by Karen Z,Sizes 20W-28W

I'm not familar with AA sizing. Can I assume the US sizes are 10-18? Thanks

I'm just getting back into sewing after many years. Will this be a good pattern to get me started again with little frustration?

Does the pattern come with sewing instructions?

Can this be enlarged to a bust size 56 inches?
