This is a size 10, flowing Bridesmaid dress by Wtoo. It's a light blue-green color (officially called Eucalyptus). There is a knee high slit that runs up the back center of this dress. The dress is also almost completely backless.
This dress style is not fitted. It fits more like a size 8. It has been altered to be taken in around the bust and let out in the hips.
There are no snags or tears in it.
