Not all reports are in but here's what I could find Monday morning after the 2009 Primetime Emmys.
Please feel free to add more in the comments area and I'll update the list. Hope I got it all correct; I scoured the 'net this morning using info from www.stylelist.com and www.instyle.com, mostly.
The list was later confirmed by a press release for the Platinum Guild which listed 24 stars who wore platinum jewels. Style Expert Michael O'Connor is the platinum star of the Red Carpet.
This is the score card thus far ... wish I saw more of my favorite designers but I do understand the hollywood buzz machine. At least we can say that shoulder duster earrings, big cuffs and one large knucklebuster rings were the winners last night. For the "year of the statement necklace" we only saw a few. I'm guessing the stylists think about how their clients will be photographed for the evening and prefer a bare necklace for some reason. There's always a reason!
