This one is one of my favorite Combinations: tapered pants which are loose enough to wear tights underneath, ankle boots and a striped long sleeve. Since its a really mild winter (atm) I sometimes can just layer a heavy knit but would never forget about a scarf. the grey one is pretty cheap with 16€, (says someone who still didn't get the hype about acne scarfs for 160€...)
I hope you like that Inspiration! What is your WINTER UNIFORM?
