I like high low hems but I agree with everyone else. This one is not tapered. I would just hem the back up a lil but to even it out. Maybe bringing it up to about mid calf.
I never cared for the hi-low hemline, but this one is too extreme. Too short in front, too long in back, with no attempt to taper it at all. I'd cut the back off, then use the fabric to lengthen the whole skirt, so it had a minimal ruffle on the bottom.
