I just received a 7 Sisters bottle I purchased on ebay for one of my 6 sisters. It is suspiciously virginal. Of blue glass, very smooth, feels soapy and slick, not a mark on it, bottom to lip. It contrasts markedly from others, of various vintages and colors, I have purchased for my other sisters.
Are there counterfeit bottles of this brand out there? Seems a likely can didate given the prices.
