I absolutely love, love, love the neutral (but slightly emphasized) eyes and soft-red-lips look. It's stunning on just about any woman, very retro glam--and versatile, too! You can wear this look anywhere, with any outfit, and any accessories. Yummy, yummy. Definitely one of my favorites.
The only way I could see it being "enhanced" is if you were specifically going for a very Hollywood, night-on-the-town look, in which case I'd recommend gold for the lids (softly blended outward with a more neutral shade like a light brown), false lashes, and a bright red lip gloss to help keep the red lips looking plump and fabulous.
It's not my favorite makeup look but I like Mary Kate's version a little better. I just think the first picture looks very 1950s and kind of old woman-y. Like a 60 year old should do her makeup like that but if you are young go for a different look. The reason I like MK's look better is because her lips are a little brighter and fun looking.
