The subject of Michelle Obama's bare arms is so important...

... that Robin Givhan must hop over into The New Yorker:

They are not outlandishly sinewy Madonnaesque limbs. Obama’s athletic arms are achievable—in between the kids’ soccer practice, the executive suite, and the grocery store. Those arms represent personal time. They are evidence of a forty-five-year-old woman’s refusal to give up every free moment in service to husband, kids, and all the nagging distractions that could have filled her days and left her tuning in to “Oprah,” trying to figure out how she’d lost herself along the way. The arms imply vanity and power: two things that make many women uncomfortable and yet are fundamental to self-confidence.
