I read the reviews before purchasing this dress.  When I got it, I was skeptical since it cost so little [even for a light summer dress and especially for a wedding dress]. I'm Chinese and definitely not busty at all and not your sterotypical skinny mini either!  Dress fit me nicely. I bought a size medium and I'm 5ft 4in and about 125-130lbs if this helps you to size it up. It goes right to about my ankles. I plan on wearing sandals with them for my wedding so it's definitely a good length for that.
The details are shown on the dress and those are the only details.  They are nice.  After reading a couple of the reviews, I expected more details then the pictures showed, but there weren't any.  Use the enlarge button to see the details, they are there and there's no addition ones the pictures leave out---so don't go looking.
Definitely get the one that is lined! It definitely would have gotten a 5 star if it was lined--without the extra cost. See through dresses should always automatically come lined. Fabric feels silky/satiny smooth.  Very comfortable.
A MUST by for the price!
