GLITZ AND GLAMOUR
Kendall Jenner celebrated her 21st birthday in Los Angeles at an intimate dinner surrounded by family and friends before heading out to star-studded, 1920s-themed late-night bash. Of course, she pulled out all the stops for her b-day outfit: a custom, shimmering $9,000 dress from Lebanese designer Antoine Salameh of brand LaBourjoisie.

Penelope Disick and North West invited some major VIPs to their joint mermaid bash. Two adorable princesses led North on the dance floor and guided the crowd in a round of "Happy Birthday." Besides keeping the party vibes strong, special guests are great for proving how humble you are by showing that you'll share the tiaras even on your special day.

COSTUMES, COSTUMES, COSTUMES
Why should you only get to choose what you wear at your birthday party? Penelope and North set an example for us all by instructing Auntie KoKo to don lavender hair for their joint celebration.

BEDAZZLING AS FAR AS THE EYE CAN SEE
If there aren't more jewels than people at your party, you've made a serious miscalculation. Khloé Kardashian danced it up with her mom, birthday girl Kris Jenner, while dazzling in a diamond-encrusted gown.

A GOOD THEME
You need a big concept. Something grand, something photogenic, something that will allow for glam costumes and cutesy decor. Jenner went full Great Gatsby for the big 6-0 — and she's currently the one to beat.

ALL ATTENTION ON THE BIRTHDAY KING/QUEEN
Even when you're taking pics with your crew, make sure the festivities still center on the birthday girl/boy. For example: Jenner is the queen of a photo she's not even supposed to be in.

The Kardashian-Jenner family knows it's not a birthday without something sweet — and we're not just talking about cake. Kris Jenner started off the big 6-0 with a big doughnut delivery. Hey, anything is okay on your birthday (especially if it falls on National Doughnut Day!).

Because sometimes your hands get tired of taking selfies. (Kendall Jenner knew what was up for her 20th b-day.)

In fact, snacks should be the party's number-one priority. For Kim's 35th, Kanye not only put together this stunning white rose cake, but also made sure there were churros on hand. "I loved it and had the best time ever, feeling so very comfortable eating churros with a bunch of pregnant women!" Kim wrote on Instagram.
