Clad in a sexy scarlet Alexander McQueen minidress, Christian Louboutin snakeskin heels and a full-face of makeup, Kim Kardashian looked ready to walk the red carpet on Tuesday.

Only, the 30-year-old newlywed wasn't on her way to an A-list event. Instead she was all decked out for a trip to an organic grocery store in New York City.

She was joined by big sister Kourtney, 32, who was also dressed to kill in a bright yellow blouse, tiny white shorts and her own snakeskin Louboutins.

The duo stocked up on healthy fare including Greek yogurt, gluten-free burritos, cookies and chips and kombucha tea.

The reality stars arrived in the Big Apple on Monday to film the new season of Kourtney and Kim Take New York.
