BROADCAST CLOTHES: The London Olympics are a little over a month away, but NBC’s three female hosts for the July 27-Aug.12 event already know what they’ll be wearing. Stylist Amy Acton, who worked with the 13 studio anchors, picked pieces from Doncaster for broadcasters Kelly Tilghman, Rennae Stubbs and Mary Carillo for their Olympic coverage. Acton said she knew it would be a “right fit.” “I love the fact that I am styling three very different women and I was able to create a specific look for each lady that suits their unique and individual style from just one clothing brand,” she said.
