But this time around, it wasn't about hair color but rather a whole new hairstyle!
Kim took to her blog today to show off the new 'do that she and her half-sister decided to try on for size and to get a little feedback from fans.
"It's fun to experiment with new hair looks!" wrote Kim along with the above pics. "Kendall and I are both trying out cornrows! What do you think... would you guys wear this look?"
No word on what prompted the gals to change things up a bit.
Perhaps they were inspired by their trip over the weekend to the Dominican Republic, where Kim and Kendall enjoyed a little sand and surf with their famous family.
