Sweatshirts are the perfect foil for formal skirts. They add just the right amount of insouciance to otherwise über-glam eveningwear, which basically means you can go batshit crazy with the accessories and not look overdone. I am personally going to dress like this for all the Christmas parties this season. On-trend, sparkly but not overdressed and, most importantly, warm: I think this is basically the holy grail of winter party outfits. You're welcome.
Pro tip: don't wear embellished shoes with full-length skirts. For one thing, no-one will see them, and for another, they will catch on the inside of the skirt all. the. time. and drive you completely insane, thus ruining both your skirt and your party mood.
