Katy Perry serves 'mermaid core' in an ivory bridal gown

If there's one thing Katy Perry knows how to do well—other than put on a blooming good performance, ofc (read: spinning bras, iconic tunes and 3D set designs)—it's stunt on a major red carpet. And today is no exception for she's only gone and stepped out wearing a star-studded fashion statement. Are we surprised? No, no we're not.

Just yesterday, the American Idol judge took to the reopening of The Landmark at Tiffany & Co 5th Avenue and chose to wear a vintage ivory-coloured Dior by John Galliano dress from the brand's 2006 autumn collection. It's very much giving bridal-meets-mermaid core vibes.

The floor-length gown featured sheer straps, a sizeable train and top-to-bottom ruffles making for a dramatic statement. I mean, will I look this glamorous at my own wedding? Probs not...

Take in Perry's dress in all its ethereal beauty:

To accessorise, Perry sported a range of Tiffany jewels, including a glistening silver necklace, diamond stud earrings and two emerald rings. As for her footwear, the singer opted to dress up her lewk further by adding a pair of matching strappy silver heels.

Later on in the evening, Perry underwent an outfit switcheroo (as one does... cazsh), changing into a strapless Tiffany blue bodycon dress complete with a sheer tulle skirt. She then went onto perform an impromptu setlist, belting a select few of her very own bangers; 'Firework,' 'Dark Horse,' 'Teenage Dream,' and more were all included.

As Perry once said sang herself, she is "a firework, a dancing flame". Cue all the fire emojis.
