These jeans are a really dark blue and the sizing is about right on the length so buy for the age of your little girl if she is of average build.  The waistband is adjustable so they can be let out or brought in to suit a variety of waist sizes but they will suit a slim shape as they are a skinny fit jean.

They have a subtle Roxy Girl logo on the front pocket and the contrasting white stitching really lifts them.
