This a Pronovias Bolera wedding dress from the 2015 collection.
Person wearing this dress was 5'6" wearing flats
This could fit someone that is also 5'4" - 5'7" depending on what shoes were worn.

This is original size 10, this was alterred to fit size 12
This was professionally alterred by a wedding seamstress to fit a size 12.
5 bustles on the back to provide longer length or shorter depending on what event.
The bustles were not attached during the wedding ceremony for a longer look
The busltes were attached during the reception so that the bride could manuever easily through the tables

This was bought used as a sample dress and worn for a wedding and then now up for sale.
The shoulder straps are not original but were installed along with the breast cups, both can easily be removed.
Along with the shoulder straps that supports the dress, crystal decorations were purchased and sewn into the shoulder straps to match the rest of the dress. In additon to the decorations on the shoulder straps, the side panel decoration crystals on the both sides of the dress were also sewn in. 

The back of the dress has 5 white buttons and 5 lace decorative flowers where the bustles attach.

As you can see from the pictures, the crystals on the shoulder straps started to snap and are now loose. Once again, there were not part of the orginal dress but were sewn in during the alteration and can easily be removed.

A few pictures show the dressing hanging up on the wall so that you can see the bustle system attached and not attached.

In addition to adding pictures of the actual dress, I included some pictures that I was able to find online of the dress.
