In winter I always, and I mean always, wear a thick jumper (or sweater, as you guys like to say in the US :p) and a scarf! Those are my absolute favourites, especially wool jumpers... So cozy haha :) I like to wear thick jeans, and if it's really cold, I tend to layer a pair of leggings underneath them - that's my secret in winter. I also love putting on fluffy socks with Doc Martens, a fleecy parka and a beanie.
Similar outfits but with long-sleeved tops, or a vest under my blouse; tights under my dress or skirt; making sure the tights and vest overlap! Plus I have a Hell Bunny winter coat I really like and wear all the time outside when it gets cold
