It's too late to delete Anne Hathaway's pink gown from my list, alas. When I saw it on TV-recap shows the next day, I noticed the tackiness of the pointy darts. Why those darts???
Hathaway replaced the Valentino gown that she had been planning to wear with the pink Prada at the last minute because Amanda Seyfried's Alexander McQueen was similar. In Exhibit A of celebrity "more-than-we-needed-to-know"-ness, Hathaway's camp released a statement to that effect after the Awards. Seriously.
So there probably no opportunity for her team to scrutinize the dress as it should have been. Hathaway has a longstanding relationship with Valentino and I'm sure that dress has been pored over for weeks, perhaps months. The Prada looks like it was thrown on, and not even properly fitted, unfortunately.
