I love the overall Girl Rocker look. The top is another H&M loss leader - they gotta be losing money on this blouse. That kind of pleating detail is labor intensive and takes a lot of fabric but it is still an inexpensive top.
She said the same thing as a lot of you about shopping at H&M - the music is too loud, the store is messy, and she has to fight through a lot to find something good but when she does it is usually a real gem.
