The "cute but cas" look is the divine proportion of fashion. When the balance of simple accessories and make up details can anchor your outfit and make you look effortlessly chic or throw you off into that egregious territory known as "trying too hard".
Cute but cas is the perfect outfit for first dates. When you want your outfit to say, "Hey, I'm cool, collected. I like you and I'm totally not imagining where you'll be proposing in 1.5 years."
I think the outfit above perfectly captures cute but cas. You could totally wear that to a Knicks game at MSG, sitting court side with Chris Rock and Natalie Portman. And at the end of the game, you could book it over to a club like 40/40.
Omg I am so old that the only "cool" club I can think of is 40/40 Lolzzz.
