Herve Leger metallic black strappy dress

Black metallic with atypical straps. Can't take a good photo of it to save my life!! I wanted the strapless one FOREVER but couldn't find it so I bought this one and never wore it. Then, I found the strapless one so I am selling this one. It's super cute. Priced at $500 so that Posh can authenticate for you, but willing to sell for $400. Please note that I can usually only ship out on Tuesdays, but sometimes sooner. Sorry.
