New with tags Ganni Shiny Tech Strap Midi Dress, unworn — I bought this from a boutique online but it is too small for me and couldn't return. Beautiful and chic material with contrast lace-like seams. I would love this in a different size if I can find it. Size guide attached. This fits more like a 4/6.
