Margot Robbie won more than Best Actress in a Comedy at last night鈥檚 2018 Critics鈥 Choice Awards: She also won big in the style and beauty departments! Clad in a smocked strapless cream and Chanel gown and Jimmy Choo sandals, the I, Tonya star kept things classic up top, too, stunning in an asymmetrical topknot. We got the deets from her stylist, Bryce Scarlett, on how to create the look at home, and it will only cost you $15.

鈥淭he whole look was inspired by the fact that Margot was wearing Chanel and for hair and makeup we were trying to emulate a classic, Chanel aesthetic,鈥 Scarlett dished.

He was also going for carefree, since the overall mood was a bit more lax than the recent Golden Globes Awards. 鈥淔rom the perspective of hair only, I think this is a much more undone moment 鈥 there鈥檚 a lot more ease to the looks,鈥 he said.

The hair guru began by coating the actress鈥 strands with the TRESemm茅 Expert Repair & Protect 7 Pre-Styling Spray with Biotin ($5) to ward off any heat damage.

Next, he got all up in her roots with the brand鈥檚 Two Extra Hold Mousse ($5), creating volume by blowing it dry with an upward-pointing nozzle before scrunching the Australian beauty鈥檚 locks with water to 鈥渋nfuse moisture and regain some of that natural wave.鈥 He followed that up with another blow-dry sesh (this time using a diffuser).

After the drying phases were (finally!) complete, the celeb stylist blasted the 27-year-old鈥檚 entire head with the new TRESemm茅 Compressed Micro-Mist Hair Spray Hold Level 2: Smooth ($5) to give it a smooth, non-crunchy finish.

Once he was prepped and ready to style, the pro pulled the star鈥檚 shoulder length hair into a high off-center ponytail, allowing some strands to 鈥渇all out around the nape of the neck.鈥 Finally, he twisted the blonde bombshell鈥檚 pony into an undone bun, using a simple black ribbon to tie a bow around its base.

To ensure this 鈥榙o lasted all night without looking stiff, the style was finished with another coat of the compressed micro-mist spray.

As a finishing touch, additional strands were pulled out to frame the starlet鈥檚 face for a perfect undone, done look.

Now, if you鈥檒l excuse us, we鈥檒l just be in the bathroom, practicing our off-center ponys.
