Sheer and Now: Lauren Conrad has such gorgeous hair. So long. So shiny. So healthy. So touchably soft. Oh, you didn't notice? You were too busy squinting at what's going on beneath her flimsy, floor-length gown? To the casual, peeping observer, Lauren seems to be seizing her red-carpet moment by posing in nothing more than her unmentionables and Morticia Addams' most diaphonous peignoir, but in reality (a concept the former "Hills" star is wholly unfamiliar with), she's styling a cover-up over a bikini for a poolside promotional event in Las Vegas. Not that anyone staring at the outline of her belly button would care about such mundane, if decorous, details. All they see is a pretty blonde flashing an itty-bitty bra and even ittier and bittier panties. Lauren's look is both too much and too little for Sin City, where appropriate middle ground can be found somewhere between an overtaxed tube top and a retiree's "Circus Circus"-sized caftan.
