There's nothing better than finding the perfect LBD. Even better is it costs less than $13. This ribbed dress from F21 is currently my go-to dress. I can dress it up with heels, wear it with some jewelled sandals (pictured above) or throw some sneakers on with it. It's honestly the most versatile basic a girl could own. I suggest everyone go pick one up. I should know... I've got two in my closet.
