Need further proof that Ariana Grande is ready for the style big leagues?
Just take a look at the gorgeous dress the singer wore on the 2015 Grammys red carpet Sunday night:
The "Love Me Harder" songstress turned heads in a white gown that featured strategically-placed cutouts, a silver detail that channeled the best of disco, a slit up to there and a stunning open back. Ariana styled the beautiful dress with white pumps and a slicked back high ponytail.
Joining the 21-year-old brunette beauty was beau Big Sean, who looked quite handsome in a black suit, which contrasted nicely with Ariana's bright gown.
Look at how cute they are together:
