When we're busy baking, decorating our apartments, and gift shopping for everyone on our "nice" list, planning holiday party outfits tends to get pushed to the end of our to-dos.

We're investing in quality ensembles that fit the bill for all of our RSVPs and work in our wardrobe long after the ball drops. After browsing the dark floral dresses, silky jumpsuits, and pajama-inspired sets from Thakoon — a.k.a. the non-cliché holiday pieces we've been looking for forever — we can nix "find a killer outfit" from our seasonal worries.Intrigued?
