Kim Kardashian: Nippy At 90 Degrees

Kim Kardashian didn't look like she had any cares while at the Revolve Summer Party in the Hamptons this weekend. None of the guests could've guessed by looking at her that Kim was getting ready to start a white-hot feud with Taylor Swift.

Instead, the reality-show star clad her curves tight! The hostess — who arrived by private plane — didn't seem to care about the temperature edging into the 90s. But she chose an outfit that sure suggested she left her bra back on board!

Kim was mingling at the party for the online shopping site while sporting a long-sleeved knit dress that rolled up in a mock turtleneck.

To keep cool, Kim made a concession by sporting bizarre ripped jeans that doubled as boots — while her makeup held up admirably!

Kim's retro Sweater Girl look also helped her stand out in a crowd of guests who mostly opted for shorts or lightweight summer dresses!

It was probably just another sacrifice for fashion, but Kim managed to fulfill her duties without breaking a sweat. She may have lost a few fans while defending husband Kanye West from Taylor, but nobody can say that Kim doesn't work (it) for a living!
