Flowergirl Question- sizing?

My daughter is in a wedding in June. The wedding salon made me order the dress when she was 3 months old(I know very early). When my daughter was born she was born at 9 lbs. In December we ordered her a 12 months dress. Now- at 6 months old her Easter dress is already 12 months. What are the chances this flowergirl dress fits her in June. I am very nervous and when I called the bridal salon they told me there was nothing they could do(I figured that much). Can they let it out if needed? or add extra fabric or something? This bridezilla is going to flip but it was not my fault. I also refuse to buy another dress. This one already cost me a pretty penny. Has this ever happened to anyone?

Re: Flowergirl Question- sizing?

If it is too short they can always add a panel or lace to the bottom of the dress...they will probably be able to let it out a little bit but not much..they could possibly split the seams and add fabric that way if they had too. If they wont accomadate you you could probably find someone else who will...Do you have the dress yet??? Sizes really vary from manufacture to manufacturer perhaps its more true to size than DD Easter dress.
