Print mixing can be tricky, I'm normally not very adventurous in this field. But when I browsed trough j crew the other day I came across these pants and sweater and fell in love. I think the trick is to keep the rest minimal and classic.
Sweater, pants and bag j crew. Blazer Alexander Wang, boots Acne, Ring Maison Martin Margiela, Ray Bans Wayfarer and Chanel Black Satin.
J crew still has this promotion going on with free shipping, free returns and duty free shopping worldwide until end of December, but the pants are not available anymore at jcrew but you find them at net-a-porter, click the link above.
