The trick with short hair updos is not to overthink it. In this case, Olivia Holt fakes fullness (and therefore length), by simply stacking three ballerina buns at the back of her head. The result? Triple the elegance. To steal the look, created by celeb stylist Riawna Capri:

1. Start by creating three separate ponytails at the back of your head. One at the crown, the middle and the base of the neck.

2. Twist each ponytail, and wrap it around itself to the right. Secure each of the buns with bobby pins and a spritz of hairspray.

3. You can keep the look causal and pluck out a few stray pieces here and there, or tuck everything in for a more polished look.

When Stone debuted her short bob with side-swept bangs, she also gave us a new updo idea for short hair. The actress left her bangs loose, and the rest of her hair was rolled at the nape of the neck and tucked under, which is incredibly easy to recreate.

1. Apply a blowout cream to damp strands (we like Garnier Blow Dry Perfector Straightening Balm, $4.29, and blow-dry hair smooth and straight.

2. Once dry, create a deep side part, and flat iron bangs (if you have them).

3. Grab the hair just above your ears, and gather the hair by twisting it towards the head, and continue to twist until you reach the nape of the neck. Do this for both sides of the head.

4. Take the remaining hair at the back of the head and tuck it into itself at the nape of the neck -- creating a messy bun. Use bobby pins and firm-hold hairspray to lock the twisted, short hair updo in place.

So you can't exactly rock true boxer braids when you're sporting ultra-short hair, but (no surprise) Ruby Rose has her own short hair spin on the badass style. To get the look:

1. If you have short layers, start with second day hair or apply a styling cream like Shea Moisture Coconut and Hibiscus Curl Enhancing Smoothie, $12.99, to give hair better grip, and create a center part.

2. Craft two Dutch braids on either side of your part, and secure the plaits with bobby pins.

3. To get that sexy, sleek look Ruby Rose is known for, reach for a gel like Matrix Style Link Super Fixer, $18, and smooth down the entire style.

Watson shows us you don't need waist-length hair to style with braids. Her double French braid twist works best on shoulder-length hair, but if yours is a little shorter, try making the braids smaller and tighter, then tuck and pin the ends underneath the braids to hide any wispy pieces. To get her look:

1. Start by French braiding the left side of the head. As you move towards the back of the head, sweep the French braid down towards the nape of the neck and secure with a clear elastic. The tail of the braid should remain free (we'll come back to that later.)

2. French braid the right side of the head, and work it towards the crown of the head. Secure the braid with a clear elastic and keep the tail of the braid free.

3. Now for the hair magic. Take each of the braids' free tails and swirl them around each other in the middle of the head. Secure the look with bobby pins and lock it in place with a hard hold hairspray like Got2b Glam Force Hairspray, $6.99.

If you made a major chop, go for the faux look. Supermodel Coco Rocha demonstrates the ease of getting a high fashion style that will fool everyone into thinking you somehow managed to create an updo. To get her look:

1. Saturate wet hair with a gel like Redken Hardwear 16, $19.50, and create a deep side part.

2. Use a comb to brush your bangs away from your face, and comb down the rest of your hair (to create a nice sleek surface.)

3. Then, channel your inner rock star and rock your badass vibes all night long.
