Rolling up your sleeves is commonplace, whether you are in the office or out working in the heat. However, I'v noted a sort of equestrian trend recently involving rolled up pant cuffs and not just enough so that your pants don't drag against the floor, but well above the ankle. The outcome is similar to capri cut pants, but with more flexibility to roll the cuff up or down.
I think it's a really nice way to highlight a high top shoe such as the boots I'm wearing above. It might also be an interesting way to introduce a colored or patterned sock
FYI: This blazer/coat is one of my favorite pieces...bought it at the thrift store for under $5!
