I always get vexed by yellow. I think it's a tough color to pull off. But seeing this photo and the way it perfectly breaks up Summer whites--and transitions you into Fall--I'm thinking the cheery hue is actually universal. I love the print on the scarf and the way that yellow comes but in patterned and unexpected forms. The outfit is still light and bright, but dark oxfords and a wonderfully warm oversized cardigan would make this the perfect Fall outfit.
