First looking at Gwen’s eyes I’d say you could re-create this with a faithful paintpot from MAC. I thought the shade Indianwood would be perfect for this slightly gold metallic look. Blend this up to your brow bone and blend in a lighter more pearlescent shade like Let’s Skate. This will create a lovely effect and it can be done with minimum effort.
To draw more attention to the eyes, I’d say Gwen has opted for some falsies. I love these double definition ones from Eylure, they aren’t too over dramatic but are enough to frame your eyes and make them pop.
To re-create that Stefani glow you should give Chanel Vitalumiere a try. It gives you a flawless even finish and also that healthy glow that Gwen has. It has some moisturising properties too and is meant to feel like a second skin which will give you the same natural look.
Lastly we look at the statement lip, Gwen moved her way from her usual red lip and went for a vibrant pink. To match her outfit of course. This one from Illamasqua in the shade Euyridice looks like an almost perfect dupe. I love the formula of these lipsticks and they last forever, enough to get you through any occasion.
