Gwyneth Paltrow wore a tight, strapless number for Baby Buggy's Summer Dinner on Saturday evening in East Hampton. She was surrounded by friends and family for the bash, like her mom Blythe Danner as well as Jerry and Jessica Seinfeld. Baby Buggy, a charity that equips less-fortunate families with the gear and clothes needed to raise a child, was established by Jessica back in 2001, and Gwyneth has been a longtime supporter. The meal was sponsored by designer Reed Krakoff, who was seen chatting with a fresh-from-NYC Rachel Zoe. Rachel was decked out in an outfit from Reed's namesake collection. While in the Big Apple, Rachel Zoe shared her beauty secrets with us at an event for Exude lipsticks. Reed Krakoff is also the president of Coach, which had another connection to the dinner — Gwyneth Paltrow's new Coach ads, which are being published in foreign countries, came out earlier this month.
