The arrival of September means saying goodbye to the summer, and hello to the fall.

Kris Jenner said her goodbyes with a sexy selfie, while wearing her bikini in the pool. The photo shows where the Kardashian girls get their figure! They got it from their mamma!

She posted the photo to Instagram along with the caption, "Last day of summer gonna miss you."

Kris is rocking a bright blue triangle bikini, with a beautiful statement necklace. 

Kris wasn't the only one posting bikini pics though! Her daugher Kendall showed off her bikini-bod, with a photo shoot posing for a Columbian swimwear brand, Agua Bendita - which she shared on her Instagram too.

You know what they say: like mother, like daughter! Looking good ladies.
