Sharing the below close-up snap with her 2.3 million Instagram followers, Keegan wrote "My favourite look of 2015. Thank you Krystal Dawn and Lisa Laudat," (her hair and makeup glam squad).
If you want to recreate Keegan's exact look, you're in luck! Her wedding makeup artist Krystal Dawn also took to Instagram to share a photo of the makeup, with a full list of products used in the caption.
For the base, she used Nars Sheer Glow Foundation in a medium and dark shade, blended and applied to create a subtle highlight and contour.
Under the eyes, she applied Bobbi Brown Corrector in Peach, Estée Lauder Double Wear Brush-On Glow BB Highlighter in Medium, and the brightening powder from the Laura Mercier Undercover Pot in 02.
On Keegan’s eyelids, she applied Laura Mercier Metallic Crème Eye Colour in Gold, with the bronze sparkling shade from the Tom Ford Golden Mink Eye Colour Quad on top. She then applied Kiko Infinity Eyeshadow in Mat Cocoa in the crease and Bobbi Brown Long-Wear Cream Shadow in Bone along the brow bone.
Next, Dawn applied Bobbi Brown Long-Wear Gel Eyeliner in Espresso Ink along the top of the lashes with a flick, and in the waterline. She also used Kiko Cream Crush Eyeshadow in Pearly Chocolate as a soft bottom liner.
To finish the eyes, she added some Ardell Demi Wispies false eyelashes, then finished with Estée Lauder Double Wear Zero-Smudge Curling Mascara.
Dawn then used Charlotte Tilbury Filmstar Bronze & Glow for a subtle contour, and Bobbi Brown Blush in Nectar on Keegan's cheeks. For a subtle shimmery highlight, she used Urban Decay Naked Illuminated Powder in Aura on her cheekbones and eye tear duct.
To create Keegan's nude pout, Dawn lined her lips with Kiko Precision Lip Pencil in Caffe Latte and applied No7 BB Lips Beauty Balm in the shade Ballerina.
Finally, she applied Iconic London Gold Dry Body Oil on Keegan's body and neckline for a beautiful sheen.
