H&M Charity UNICEF Kids' Collection

There's nothing better than knowing that your purchases are helping a cause. Last year, we didn't think things could get any better than H&M's All For Children collection, but that's because we hadn't seen this year's designs. On Oct. 18, the Swedish retailer will introduce its 2012 All For Children collection to benefit UNICEF at 300 stores worldwide.

While the collection includes dressed-up designs like a pink bow-detail dress, a fake-fur necktie coat, and printed tops for girls, as well as blazers and colorblocked sweaters for boys, it's the costumes and fantasy pieces that we're drooling over now. Wizard hats, magic wands, rabbit ears (and scarves), and flamingo heads are the perfect Halloween accessories for kids who don't want to go the commercial route this year. And the wall stickers and playbook just add to the fun.

As it did last year, H&M will donate 25 percent of the sale of each garment to UNICEF's work in Bangladesh to promote education and improve children's health in the slum areas around Dhaka, including those that help make the discount department store's clothes.

To help kick off the collection, H&M will host celebratory events in New York and Chicago on Oct. 18 and in Los Angeles on Oct. 20, with food, music, face painting, and the opportunity for kids to create their own iconic UNICEF Trick or Treat boxes.
