The fashion experts and royal watchers are waiting to see Pippa Middleton in her wedding dress on May 20 and reports suggest that they will not be disappointed. Pippa will wear an "elegant and handmade" bridal gown for her wedding day.

After Kate Middleton, now her sister Pippa's wedding has become a grand affair and royal watchers are keeping an eye on all the minute details of the wedding, including the bridal dress, guests, and the maid of honour. And while all the details are kept under wraps, sources have revealed to E! News about Pippa's wedding dress.

There were rumours that British fashion designer Giles Deacon had met Pippa and her mother in November and sparked speculation that he will be designing her wedding dress. However, the designer at that time dismissed all the rumours. "I can never really comment on rumours. Until things are confirmed it's just rumours," he told Hello!

But the latest reports suggest he has indeed designed her wedding dress. "The design is very simple, elegant and it's all handmade," a source close to Giles Deacon's team told E! News, adding, "very few people have seen the finished thing."

The source also revealed that Pippa had done the trail of the dress five times before, as she has lost some weight. The younger sister of Kate was spotted taking Pilates classes at a fitness centre.

Meanwhile, apart from her dress, there has also been speculation about the page boy and flower girl. According to Daily Mail, Prince George will be the page boy while Princess Charlotte will be the flower girl.

The wedding ceremony will take place at St. Mark's Church Englefield in Berkshire and Prince William, Kate, Prince Harry will be among the royal guests.
