Celebrities stepped out in style to attend the 2018 iHeartRadio KIIS-FM Wango Tango by AT&T at Banc of California Stadium in Los Angeles on Saturday.

The annual concert brought together the hottest artists on one stage, but prior to them performing, some showed off their fashionable ensembles on the blue carpet.

Meghan Trainor perfectly matched her pink hair with a blush-toned jumpsuit that featured a plunging neckline, a yellow belt and slits that showed off her black boots.
