And with each change, the singer seemed to go for a look that was even sexier than the last.
So of course Ellie was at one of her hottest moments at the BRIT Awards' Three Six Zero and Roc Nation after party, where she arrived wearing a super slinky LBD that had sheer geometric shapes down the front and sides!
But when you consider the shortness of the dress and the sloshy-ness of the party, it was probably a good thing she was wearing some. Wouldn't want her award-winning evening to be ruined by an unfortunate crotch-shot!
Also, loving how she incorporated a body chain beneath her ensem!
