We've been thoughtfully planning our holiday outfits for weeks, right down to the perfect party shoes. Now that it's quite literally time to kick up our heels, we figured we'd spill which ones we'll be wearing this year.

We struck gold with Jessica Simpson's festive selection of heels (and flats!) for every type of event. So consider these nine pairs of shoes your official reminder to RSVP yes to every invite.
