We were ecstatic when adorable tights showed up on every runway's leggy muse back in September because it meant that we had a new way to liven up our 9-to-5 dresses and put an end to frumpy office-appropriate bottoms. Then we saw Marni's new take on the sheer accessory... and nearly panicked. These black, sheer, knee-high socks seem like a strange hybrid between a call girl's on-hour hosiery and a Mad Men exec's off-hours trouser sock. But what's your judgment? Do these knee-highs scream sexy business class, or are they just risky business?
