British fashion designer Julian Macdonald unveiled a diamond-embroidered wedding dress worth more than £4 million pounds today at London Fashion Week.
The theme for the show which featured several figure-hugging outfits and babydoll shift dresses was flowers mixed with tattoos.
Macdonald revealed his inspiration was a mermaid living in a tropical sea who "lures a handsome man" and he was pleased with the finale wedding dress which featured real diamonds and fresh water pearls.
"I don't know if I can walk in a straight line that well," said Styles. "I might fumble around, so maybe not. Maybe I'll zig zag, or switch it up a little bit."
Styles, 19, was rumoured to be dating Delevigne, 21, after they were spotted together at several parties during London Fashion Week.
He turned out to watch Delivigne at the Burberry show where he was spotted sharing a joke with Sienna Miller and Paloma Faith on the front row of the show, but denied that he and Delevigne were an item.
"People talk about anything really, but we're just friends and stuff," he said. "She is a lovely girl."

Model Lily Cole kicked off Vivienne Westwood's Red Label show at London Fashion Week with a modern dance.
Westwood said the solo performance was a metaphor for their climate change concerns; a theme which ran through the show.
Westwood said: "I just use fashion as an excuse to talk about politics. Because I'm a fashion designer, it gives me a voice, which is really good."
The show closed with an appeal to the audience to fill in a climate change postcard to send to the UN Secretary General Ban-Ki-moon.
