The 'Suits' actress - who has been dating Prince Harry since last summer - has been invited to her boyfriend's sister-in-law and her fiancé James Matthews forthcoming ceremony on May 20 at St Mark's church in Engelfield, England and she is already planning which outfit she is going to wear for the big day.

Sources have told E! News that she has been to a dressmakers in her hometown of Toronto, Canada and though there are no further details on her choice of ensemble, she is expected to wear a hat for the formal occasion.

The 35-year-old beauty was previously only expected to attend the couple's after-party, but The Daily Telegraph newspaper recently reported that she will attend the full wedding with the 32-year-old flame-haired royal.

Meanwhile, Prince William's children, Prince George and Princess Charlotte, will play major roles at Pippa's forthcoming nuptials to fiancé James Matthews.

The 33-year-old socialite has asked her sister Duchess Catherine and brother-in-law if the three-year-old royal can be a page boy while the two-year-old princess joins the bridesmaids, Kensington Palace has said.

It was initially thought that Catherine would be her sister's matron of honour when she gets hitched next month but it doesn't look like she's taking on that role - even though Pippa was one of the Duchess' bridesmaid at her lavish ceremony when she married William in London in 2011.

Although she hasn't got a major role in Pippa's nuptials, Catherine will attend the ceremony with her husband.

Pippa's wedding is no doubt set to be extravagant as it was recently claimed that there will be "no expense spared" when it comes to the wedding.

A source said previously: "It will be blingtastic. The best champagne, Krug or Bollinger, and a specially devised champagne cocktail.

"Pippa and James have a penchant for Blanc de Noir Tillington 2009 from Nyetimber at £75 a bottle - and wonderful food. No expense will be spared. This isn't a bangers-and-mash, sitting-on-hay-bales affair. Pippa is hardly a floaty bohemian type."
