This new H&M ad is causing major waves, and not just in the fashion world.Designed to promote a message for sustainable fashion–recycling clothes through H&M's global garment collection initiative–the clothing retailer's latest ad has also torn down some barriers so rapidly, you won't know left from right after watching it– and that's a good thing.The ad, entitled "Close the Loop," features a colorful ensemble of models from a wide array of backgrounds, shapes, and sizes. You can't help but quickly become a part of the diverse world–very much our own–the commercial paints, coupled with rule-bending imperative statements that convince the listener to ignore the set rules of fashion and do their own thing."Wear a hat indoors," encourages the ad's narrator in his playful, grave voice. "Stand out. Blend in [....] Wear socks and sandals." The commercial moves through monotonous and dreary scenes that are illuminated by its cast, largely dressed in bright or clashing colors, looking fashionable or positively rebellious: looking like themselves.And yet the ad is garnering most attention for its controversial themes.
