This outfit would be very easy to recreate with items you already have in your closet, but if you still need some of the elements - I found some options for you. You'll need a black long sleeve tee ($19.50), straight leg jeans to roll up for a similar look ($59.50), and Converse Hi canvas sneakers ($45 on sale). Click on any of the photos to purchase.
For accessories, I found a similar bag at Wal-Mart (click HERE to purchase) for $53, as well as a white scarf ($10), and shield sunglasses ($7.50). You can click on the photo of the scarf and sunglasses if you wish to purchase those items.
