Multi-billion dollar fashion conglomerate Jones Apparel Group has a serious sicko on staff. Apparently someone keeps leaving used tampons in the office hallway and it's become such a problem that a top exec is sending out company-wide emails about it.

• The Costume Institute Gala is a mere five days away. Fashion Week Daily has a roundup of who's going, who isn't, and what everyone will not be eating. (Chicken, in case you were wondering.) [FWD]
• The Observer on Alexandra Kotur, the "Viscountess of Vogue." [NYO]
• It seems some women are so addicted to the discount designer site Gilt Groupe that they're practically going bankrupt buying stuff they really don't want or need. [TDB]
• It's official: Madonna is attached to Louis Vuitton's new ad campaign. [Grazia]
• Isaac Mizrahi rang the closing bell at the New York Stock Exchange yesterday. The market has been having a surprisingly solid week so far. Could the two be connected? We'll say yes, if it's okay with you. [Facebook, WWD]

It's good to be Rachel Roy at the moment: The mother of two—daughter Talullah was born just a month ago—is now selling a 50% share in her eponymous fashion company to the Jones Apparel Group, the fashion behemoth that controls Nine West and Anne Klein, among other lines. Roy's label, popular with youthful socialites and the occasional celeb, was founded a few years ago with backing from the designer's rap mogul husband Damon Dash. Now it will now go into major expansion mode with new lines like shoes and perfume, freestanding stores, and even a diffusion line for women who, tragically, don't have $1,000 to spend on a dress they'll wear once.
