Robe Jackets

What is a a Robe Jacket? ((might not be the actual name)) but to me they are jackets that resemble robes since they do not have any zippers or buttons and they way they remain closed is with a tie. 

I purchased one that I am currently loving at Zara and it is perfect for this time a yea because it is still lightweight and the pattern is so fun. The one i'm currently styling has some black in it but the main colors are periwinkle & ashy purple. Since this piece is the focal point of my look I styled it with an all black underpinnings that way the robe jacket could really pop!
