New Marisa Mermaid Style Gown

I am looking for the style number of a Marisa mermaid style dress I saw at a local store. They said they don`t know the number Marisa uses. It is not on her website either. It is supposedly a new dress. It is strapless and some small crinkles are made into the dress at the top down to the waist. It is also fitted at the top and poofs out more at the bottom (thus mermaid style hehe). Anyway the top is very slightly v-neck (it is so slight I don`t even know if I should call it that..just not good at describing things!).. The back has buttons down the back over the zipper. If anyone knows the style number on this dress could you please let me know! I appreciate it! Thanks!
