Hi,there!I've done this look for a few times,I think it isn't that hard to do
MAC describes:
Eyes:Groom your eyebrows and set them with Brow Set in Show-off.
Apply Summer Neutral es and Gold Dusk Piggie to your eye lids using a 252 brush.In the crease of your eye,combine Light As Air Powerpoint EP
,Fountainbleu es with a 239 brush and blend thoroughly into the crease.Then apply Softwash Grey Piggie with a 217 brush,blend gently along the crease.Line your lower eye with Light As Air PP and Fontainbleu es with a 242 brush
Lengthens your lashes with Pro Mascara in Coal Black on both upper and lower lashes.
Cheeks:Mixing Shell Pearl and Sunsparked Pearl Beauty Powders onto the cheeks with your 116 brush for a hint of summer
Lips:Line your mouth with Stripdown Lip P.Coat lips with Tanarama Lipstick using a 316 brush and follow with c-thru Tinted Lipglass
Thats the offical mac description-in my opinion the most important part of this look are the Piggies and I only use 2 brushes for the eyes(yes,I'm a lazy one
Your skin should glow a bit,cause its a real summer look,so take some light self tanner or glowing powder.
I apply first a good base like mixing medium for better holding
Then I apply Gold Dusk onto the hole eye lid but not to high(just to the crease) with a large shader brush.
Then I take my finer shading brush and blend some Softwash Grey into the crease and a bit wider than my eye lid actually is,also like eye Pencil.Then I apply Softwash Grey at the lower eye,fine in the outer part but getting thicker to the inner lower eye ,lengthening with Mascara the lashes and take peachy blush and nude lips.
Just as a simple version if you are not willing to buy the hole collection
please apologize if my english description has some faults
Hope it helps a bit
Enjoy playing with the colors...
