This is what I wore to church on Christmas day. I literally just threw this on since I had like 45 minutes before mass was to begin (I got there with time to spare, plus it was 8am in the morning, no worries about overcrowding). I threw on my bomber jacket just to give some coverage for the cold weather outside, but also wore a coat.
Old Navy tee, Secondhand skirt and booties, Target jacket and tights.
