GIRLS will have to join the waiting list if they want to get their hands on a "must-have" dress worn by a Disney musical star.

The floral dress, made popular by Vanessa Hudgens in High School Musical 3: Senior Year, goes on sale at Asda's George stores today.

But, shop bosses predict the replica dress will be an "instant sell out" and that, because demand is so high, girls will need to join Asda's first waiting list.

The £16 dress, worn by character Gabriella Montez in the latest installation of Disney's hit musical, is available in sizes 4 to 12 years.

It has been replicated "stitch for stitch" to the design worn in the film.

Fiona Lambert, design director for George, said: "Every young girl will want this replica dress in their party wardrobe.

"And because of the quality and the fact it's not purely for dressing up', it will be worn way into Christmas and beyond."
