Warning: you're about to be shamed by the queen of all things sassy. As if looking permanently perfect while pregnant wasn't enough, Blake Lively appeared at the Gabriela Cadena show at NYFW yesterday, one month after giving birth to a daughter (possibly called James) looking like... THIS. So – how to steal? Well, we're all about the hair. With a hint of morning-after (i.e. brushed out and slightly mattified, thanks to some dry shampoo), Blake has single-handedly helped with our Valentine's Day 'do dilemma. Other style tips to pull out from B (because she's that good): swap out cliché red and go fierce in a graphic dress. Come at me, V-Day!
