I'd say it's defintely worth it if you're in the market for a denim skirt. The fit is great, it hugs curves really well. The fabric has a nice stretch and very comfortable. It's kinda short for a pencil skirt, since it actually hits a couple of inches above my knees (I'm only 5' 2.5"). I really like that, since I normally can't wear pencil skirts due to the fact that they're too long.
The slit might be an issue if you're modest, but I'm not really so and I didn't have any issues with flashing too much thigh or whatever.
I think it runs large too; I'm a true 6 and I got this in a 2!
