The Kardashians were keeping up with the on-going New York Fashion Week and definitly kept some very short clothes for the paparazzi as well.

Kendall and mother Kris Jenner were spotted in something very similar in New York during the week.

The 18-year-old model wore this off shoulder long-sleeved top with a skirt so short you can see little part of her butt from the back view. She wore the outfit to the launch party for photographer, Russell James new book, Angels, which her naked picture will be appearing in.

Few days after Kendall's butt display, momager Kris Jenner arrived  a NYFW party, hosted by Victoria’s Secret wearing a gold filigree embroidered mini dress with long sleeves and a thigh skimming hem. But when she began hugging friends, all the cameras could see was part of her firm butt from behind!

Kris should definitely be more aware of whether or not her butt is on display, as well as put an eye on what Kendall steps out in. But the reality stars looked amazing in this leggy look and we love that they have so much fun with their wardrobes!
