Taylor Swift showed off her sexy side in a peek-a-boo LBD by Elizabeth + James, the uber fab contemporary line of the Olsen twins, while filming Tim McGraw's Superstar Summer Night special at the MGM Grand Garden Arena in Las Vegas yesterday (April 8). The special will air later this year, but wow, did our girl T. Swizzle rock that frock!

The hits keep on coming, and we're not talking about her songs from 'Red,' either. Her fashion sense has improved drastically since 2013 began and she's, well, Swiftacular with her choices.

She followed up the glamourous gold Dolce & Gabbana gown she wore the the ACMs ceremony on Sunday (April 7) with this cute LBD -- that's fashion speak for 'little black dress' -- which boasted three-quarter length sleeves and accentuated off her stems.

It has sheer panels on the sides and arms and a slightly open back, showing a little skin. It was sultry since she didn't show too, too much. It left just enough to the imagination.

While it was a monochromatic look, it was anything but basic or boring.

She wore Jean Michel Cazabet heels, which were strappy and further upped the sexy quotient.

T. Swizzle also rocked her signature cherry red lips and heavy bangs, with a little bit of wave in the rest of her hair. Her 2013 stylist deserves a big ol' raise.
