Taylor Swift served as maid of honor at her best friend Britany Maack's wedding in Pennsylvania on Saturday, February 20. The "Out of the Woods" singer looked beautiful in a pink Reem Acra long dress featuring a plunging, hand-embroidered bodice.

Some pictures obtained by Mail Online showed Taylor assisting Britany, including holding her hand bouquet and her veil train. She styled her bob hair in kinky waves and sported her signature red lipstick. Britany also opted for Reem Acra, wearing a traditional-looking, short-sleeved silk taffeta ball gown and cathedral-style veil.

At one point, the "Blank Space" hitmaker was spotted sweetly embracing a brunette gal pal, who was also a bridesmaid at the nuptials.

Taylor told PEOPLE back in May, "I've never been a maid of honor before. This is my first time, and it's really, really important to me because this is my best friend, who I've known since I was born. And she's marrying [Benjamin LaManna] someone I've known since I was 4."

She added, "Reem does the most amazing bridal designs, and Britany and I were looking through Vogue, and she pointed to this one gown, and I was like, 'I wonder if we could go to the showroom?' [It was] the best day ever. It was so amazing!"
