For nothing says casual like stripes do, an instant lifter on short of new looks days and endless possibilities to pair it anything you can find in the closet.
A couple of things to keep in mind
If you are going horizontal,opt for a size bigger.
For stripes dress look - add one pop of color with accessories as emma griffith and Jessica Szohr.
Wear it as a single piece,very few can carry off a head to toe stripes look.And pair it with solid colors.
Pair with a well cut jacket for structure if you want a cleaner look.
