Cinnamon is considered the most Christmas-y smell around Christmas time, as are orange and clove. Rose is considered the most summertime-y. (Click the link for more!)
I change my fragrances throughout the year to put me more in the mood for the season - I love citrus in the summer - but I do have my staples. Clementine Cupcake and Cream Cheese Frosting are alway staples, and I always love Oatmeal Milk & Honey for my hair care products (it smells like marzipan!)
