If you have one of those days where you look into your wardrobe and can't think of anything to wear (we all have those days!), an all-black outfit is always a great way to go. Not only does it make you instantly classic and elegant, but it also gives you a great opportunity to play around with accessories to add to your black canvas. I love these two all-black outfits worn by Olivia Palermo and Bianca Brandolini D'Adda. They are definitely going in my inspiration folder and I'll look at them the next I have "I have absolutely nothing to wear!" mini-crisis.
