Consigned at Real Real - Herve Leger in Blue

I adore this dress but it doesn't fit :( I bought it from a fellow Posher. It was a sample originally so it does not have wash instructions but it does have the Herve tag inside. I have another Herve dress that I know is authentic and is the same material. I absolutely love the sapphire blue color. I'm so sad I can't wear it. Someone please give this a new home. It's absolutely stunning in person. No flaws. In new condition. I never wore it and I think the Posher I bought it from never wore it.
