Flower girl dress

I finally got this started.  The wedding is September 15 and of course the flower girl is about 2 hours from me.  The Grandma/Mother of the Bride thought she got me everything I needed to make the dress but misread the pattern.  I have 2 5/8 yards of fabric and need 4 1/2, I have no lining and no netting.  I am feeling stressed about how this is going to work out so I am very anxious to be able to post the finished product.....soon!
