According to the fine print this H&M coupon cannot be applied to their designer collaborations or special collections. I just tried out the code however and it DOES seem to be working on the H&M Paris Show Collection that I mentioned yesterday.
If you don’t love shades of black and white as much as I do, H&M might be a bit of a frustrating shopping experience for you right now. I could seriously buy one of everything they sell because I love the lack of color. I’d start with this Knit Sweater, which literally turns chevron on its side. Normally $29.95, it’s $26.95 after the discount is applied.
