Defining your style is one key factor to always consider whether you're out shopping. Here's my guide to defining your style....
1/ Pin, pin, pin. Pinterest is one of my most used blogging tools and actually one of my favorite social networking/media sites. Create a board and pin things that appeal to you. Once you're done, take a look back at what you pinned and analyze what it is that you really like about each image. From there, you can list any characteristics or traits that you like.
2/ Consider your personality. Determining whether you're an outgoing/shy/adventurous/preppy person can help you figure out what your style truly is.
3/ Gather up all the characteristics/traits and come up with your style. Example: I have a feminine, streamlined, and modern style with a vintage twist.
