Costelloe thought to have designed Zara Phillips' wedding outfits

Irish fashion designer Paul Costelloe has been dropping some heavy hints about his involvement in the Royal Wedding.

He revealed earlier this week that one of his creations would be worn at the ceremony, but remained tight-lipped about who he had been working for.

But with hours to go, he has hinted that his design was tailored for one of the younger, athletic members of the family.

And this was his reaction when asked if it might be showjumper Zara Phillips: "You're getting very hot, yes. It's a coat and dress…and then I did her a lovely dark navy ballgown for the evening ball," he revealed.
