We all have a little jersey dress in our closets or jean and a t-shirt. I simply changed up the look with adding a scarf. When I buy scarves I make sure I can wear them as a shawl or wrapped around my neckl. I also traded my sandals for booties. I have also noticed myself wearing jeans and a tank and always throwing in a little shawl or scarf into my bag.
I personally own far too many scarves, probably because you can wear them fall, winter, and spring. They seem to always be a good idea. As my style has evolved and matured I tend to favor larger prints like this blue plaid scarf.
