Hot stuff coming through!

While Kylie Jenner may be attempting to steal the show with her wild partying and her constant barrage of sexy pool pics, older sister Kendall Jenner is the one who keeps wowing us, even when she's just hanging out around Los Angeles.

The 19-year-old showed off her tight tum and her slender legs when she rocked a crop top and leggings to run errands around Calabasas on Sunday.

Looks like the willowy brunette was not super into partying the night away with her now-18-year-old sister in Montreal, Canada. We can't blame her -- Kendall seems like the only one who has any sense!
