Nothing is sexier than something that is subtly seductive. At the 2015 Grammy Awards, these came in the form of dresses with daring backsides.

Katharine McPhee managed to pull off a racy look in a sweet pastel pink Pucci column. The draw is in the low cut back that was barely covered with ultra-thin, crisscrossing spaghetti straps. The silhouette showed off McPhee’s svelte frame and while the front is full of detail, it was the lack thereof on the back that was even more mesmerizing.

Ariana Grande's Versace column was white-hot and full of peek-a-boo details. There was the one-shouldered neckline, the cutout and up-to-there slit, and the silver accent front panel, but it was the back of Grande’s dress that really packed the punch. We love that the singer pulled her hair up so that we could really get a 360 of the look. The back of Taylor Swift's ombre Elie Saab number was a not as racy as the other silouettes that make this style a red carpet trend, but it was the perfect accent for the gown’s voluminous shape.
