Of course we had to get the scoop on her stunning makeup, which completed this flawless ensemble with perfection. Click through the slideshow to check out each product.

Celebrity makeup artist, Georgie Eisdell gave us the deets on how he achieved the final look. "I wanted to keep Saoirse's makeup fresh, young and modern," he explained. Keeping with the trend of barely there makeup, here's how Eisdell got Ronan ready for her gorgeous red carpet debut.

Georgie started out by creating a beautiful canvas. "First, I prepped her skin with Chanel Sublimage La Creme Texture Supreme," he said ($390).  To even out her skin tone and create a flawless base I used Tom Ford Traceless Foundation ($78), taking the edge off the shine with La Mer 'The Powder' ($65)."

Ronan's skin is accented with a light flush of blush as well. "On her cheeks I used a wash of Laura Mercier Second Skin Cheek Colour in Honey Mocha ($25) to the apples of the cheeks."

For eyes, Georgie kept the color minimal. "For Saoirse's eyes, I kept the lid very light using Bobbi Brown Eye Shadow in Bone ($22) on the lid and Blonde on the lash line, blending up a little to give a wash of color," he explained. "I then brought a little of this shadow under her eye to open them up.  I finished the eye off with one layer of YSL Volume Effect Faux Cils Mascara in Black ($30)."  

Brows were kept basic as well. "I wanted to keep Saoirse's eyebrows soft and natural so I used Mac Brow Duo in Blonde ($30) to enhance the natural shape of her brows.

And for the final touch, Eisdell dressed up Saoirse's pout with a sultry shade. "Her lips were the main focus of this look and I used Chanel Rouge Allure Velvet Luminous Matte Lip Colour in La Favorite ($34) to make her lips pop."
