When I have a good pair of shoes, I wear them over and over. Whether it's nice sneakers or a cool pair of combat boots, splurge on a pair you love that you can wear over and over with totally different outfits.
Something that is in every year for me is oversized sweaters. I feel like this is the way to go if you're running late. You can just put anything oversized on and pair it with leggings or jeans and it looks cute.
