Bronagh Key may be wearing a knee-length Trelise Cooper dress, but there is another New Zealand fashion designer making a mark on this evening's royal wedding.

London-based designer Emilia Wickstead, who lived in Auckland until she was 14, will dress several guests, including Catherine Middleton's cousin Lucy Middleton.

Wickstead is also set to outfit India Hicks (who was one of Diana, Princess of Wales' bridesmaids almost 30 years ago), fellow designer Anya Hindmarch, Emma Parker Bowles (niece of Camilla) and Lady Kitty Spencer (Diana's niece).

The young designer, who has dressed Samantha Cameron in the past, told The Telegraph she is proud to be dressing such high-profile guests.

Middleton's cousin Lucy will be wearing something "young and bright" designed by Wickstead.

"She's chosen something modern and fresh. She's a gorgeous girl and very similar in looks to Kate, very beautiful with the same brunette hair. From what I understand they are very close. She was an absolute pleasure to dress."

And while the spotlight will be firmly on Catherine Middleton and That Dress - the latest rumours are that she will wear a vintage Alexander McQueen gown - Westminster will be a haven of style for lovers of young British fashion.

Lady Helen Taylor will reportedly wear Erdem, Sara Parker-Bowles will wear Osman and Samantha Cameron and UK Vogue editor Alexandra Shulman will both wear Christopher Kane.
