The fabric is a bit stretchable. However, it does not have a zipper.
While Bust 35" is the correct size as per the brand, I would recommend this dress to people who have a 32" bust. I have a 34" bust and while putting it on is relatively easy, taking it off is a 2 person job. You can easily attach a zipper for your convenience.
Front Length: 60 inches (exact height of you are 5'6") Back length: 70.5 inches
The dress has a very few beads looking loose.
You can google Jovani Gowns and find out that their gowns sell for above $600 and the average price is $850. So, this is a very expensive gown.
