It might be parka-and-snow boots season right now, but with the spring collections hitting stores this month, it’s not too early to start preparing for warmer climes.

We saw the standout piece on the spring runways of Marc Jacobs and Gucci and also in the Pre-Fall collection of one of our favorite designers, Joseph Altuzarra (which hits stores in May). Get ahead of the trend by shopping our Altuzarra-inspired take now.
