In just 24 hours, two superstar songstresses were papped in the same H&M knit!

Do you reckon Katy Perry and Rihanna were swapping style tips in the front row of Karl Lagerfeld's show?

The reason we ask is because we just found out they were both wearing the same H&M knitted dress within only a day of each other! Take a look...

Rihanna accessorised it in London with tough leather lace-ups, shades, a chunky chain and...err, a bum bag.

While Katy went for over-the-knee boots, a waist belt and a metallic gold Chloe Paddington bag.

They're both big favourites of ours, both in style and music, and we just can't decide who has pulled this high street favourite off!

You know the drill Sugarscapers! Who wore it best: Katy or Rihanna? Comments please!
