Kristen Bell proved a sheer sensation in a strapless Versus LBD cinched at the waist at the CBS, The CW And Showtime TCA Party in Beverly Hills this week.

Anna Paquin wore a square-neck (and slightly more colorful) version of the same style from the designer's fall 2011 collection (also paired with black satin platforms) at HBO's "True Blood" Season 4 Premiere in Hollywood in late June.

While I like Kristen's classy ensemble, I feel like the purple piping on Anna's style really captures the playful nature of the collection, so I'm giving this one to her.

Which style is the right way, and which one needs to hit the highway? You tell me in the comment section below.
