Taylor Swift's
embracing her sexy side!

On Monday, the "Everything Has Changed" singer attended the "One Chance" premiere and Grey Goose after party at the Toronto Film Festival in Canada.

The 23-year-old looked sexy yet chic in a white high-neck Calvin Klein Collection dress with cut-outs that definitely showed off Taylor's svelte figure. The country cutie finished her look with silver teardrop earrings and gold sandals.

The singer appears on the soundtrack for the flick. She performs the song "Sweeter Than Fiction," which plays during the closing credits.

Taylor wasn't the only star at the celebrations, Julia Roberts reunited with her "My Best Friend's Wedding" costar Dermot Mulroney at the same Grey Goose after-party -- which also celebrated the film "August: Osage County."

How cute do they look together?! It's been 16 years since the beloved romcom hit theaters but the A-list pals still look great!
