No wonder Ariana Grande didn't walk the red carpet…
She had to pour herself into this sheerly glamorous gown before her American Music Awards performance medley. Perfection takes time, people!
The completely lace number exposed the Break Free singer's black panties and bra top, giving off a cool, sexy vibe.
Miz Grande wore her hair half up, half down — no surprise there.
We wish she would've added some color or sparkle, but unfortunately Ari chose basic black and simple makeup.
Hopefully she'll surprise us with something fabulous next time!
