stylethiswhistles.jpgWe didn't have a Style This challenge last week because of the bank holiday in the UK, but it's back this week, and hopefully you'll all have fun bringing out the beauty in this baby.

This week's piece is a dress from Whistles' latest collection, and I hope the combo of navy and silver grey will be as inspiring as it is challenging. It'll be tough to avoid this one looking mumsy, but I know you can do it.

As always, the rules are simple. Log in (or sign up) to Polyvore, create an outfit based around this item, and email the link to gemma@shinymedia.com with the subject 'Style This September 1st' by the end of Thursday. I'll post a gallery on Friday and everyone can vote for their favourites. Fame and fashion fortune is then yours!

Full rules and alternative submission info can be found here, just remember to put the right date on your entry so I don't lose it!
