My favorite mini trend for Fall is the Peter Pan collar. I first spied it in the Vuitton 2011 Resort collection and then it was a big statement in the LV Fall show above. I love its sweetness and have been wearing one with little sweaters much like Alexa Chung below.
The best part is that they are just a collar or a dickey which is easy to wear under anything and does not add extra bulk. One of my favorite versions is made by CeCe Toppings– they are inexpensive, come in numerous colors and restock weekly.
