Other Spring 2016 Designer unclassified dresses

I bought this dress at a Saks sample sale as a backup but ended up going with a Romona Keveza style instead. It's a Spring 2016 style, brand new and in pristine condition with no stains or tears. I've only worn it once in the dressing room and once in my apartment to show my bridesmaids. I'm guessing a bit at the street size -- I'm normally a 2 or 4 and 5'5" and the dress is a big on me and much too long. It's essentially a fitted lace overlay over satin lining connected only at the top with buttons all the way down the back. Feel free to contact me to try it on -- I'm on the Upper West Side in NYC but also plan to be in San Francisco and Los Angeles sometime this summer.
