Blake Lively is so beautiful, she would look good in anything.
Yet, incredibly, in some colours she looks even better than in others.
See how radiant and regal she is in the light blue dress. The cool, bright colours of the Refined palette bring out her natural beauty, and allow us to focus our gaze on her face, and drown in her beautiful blue eyes. Also, with her hair up, we see the ash tones of her natural hair colour, which flatter her face even more. And yes, she is highly pregnant in this photo.
In the butternut dress on the left, however, she pales by comparison. The colour seems to be speaking louder than Blake's personality, and my eyes get drawn to her cleavage (however admirable) or to her hair (too golden-blonde), rather than to her face, which means the colour is wrong for her.
She also looks tired in the photo on the left, compared with the one on the right, in which she looks SO much more -dare I say it?- "lively"!
