If you're into fashion, this is for you. If you're into solid character growth, this is for you. If you're into working/skill/real world profession based and/or slice of life stuff this is for you. If you're into stereotypical shojo high school romance stuff look elsewhere.
I loved the anime, bought the manga and have really enjoyed reading it through. I've got no love for the fashion industry, but i thoroughly enjoyed the characters progression and the overall story. I even found myself becoming fascinated by the industry.
If you enjoyed the anime give this a shot, it really is worth the time in my opinion.
