It seems Sunglass Hut sold quite a number of sunglasses when the blinding Newsroom star Olivia Munn arrived at their store opening, prompting guests to shield their eyes from her glowing and oh-so-tanned sexy back.

Oh, our poor (but happy) eyes. The actress arrived at the opening night of Sunglass Hut in Times Square, New York, wearing a black backless and sideless gown, showing off her lovely toned physique.

Olivia picked out one of Reformation’s many back-baring black maxi dresses for the store launch, making sure to do the dress justice by putting her hair up in a curled and slightly messy ponytail.

She wore her dress with a pair of yellow “Clash” wedge sandals from Sergio Rossi (which we couldn’t really see), a pair of gold sunburst hoop earrings, a few rings, and a gold cuff.

Her look was polished with a metallic envelope clutch and bold red lips.

This is one dress that is definitely not for the faint-hearted.

Aside from its very daring show of skin at the back and sides, the skirt boasts thigh-high slits that will surely make your grandmother let out a sigh of defeat for our generation.

The material is semi-sheer, though the dress is fully lined, and does not have a lot of built-in support. Ladies, when there’s a will, there’s a way.
