Loving this season's designer looks, but finding it hard to get the look on a budget? Well, finding high fashion on a shoestring is what the Catwalk Queen does best! Here's my tip-offs on how to copy four key items and still have money to go out and show them off!

First of all comes the coveted Dior sweater dress. This is the item that sparked the revival of the 60s mod look - Sienna Miller's latest obsession now she's set to play 60s icon Edie Sedgwick in a new film - and unsurprisingly, most high street stores have cottoned on and started selling their own cut-price alternatives. My favourite is the slouchy version from Dorothy Perkins, a steal at £25. It looks fab with black tights and flat knee-high boots, but can be dressed down (and modernised) with jeans and a chunky belt.

My favourite designer, Matthew Williamson, has made the flirty babydoll dress his trademark, and constantly re-vamps it for each new season with pretty embellishment and great use of colour. This beige version (left) is beyond most budgets at £895 from Net-a-Porter, so be grateful for the clever folks at Miss Selfridge, who've created an embroidered grey dress in a similar style for £60.

The velvet jacket has always been a favourite of mine, and over the past few seasons it's been slowly working its way back towards the top of the cool radar. Marc Jacobs has dressed his version up with a ribbon belt this season (Marc by Marc Jacobs velvet jacket $358) but I think this time I actually like the cheap alternative better! Additions Direct's jacket is the most gorgeous deep red colour with a satin ribbon tie that takes its influence from a past YSL bestseller. It's reduced to an absolute bargain £26 so get in there quick if you want one!

Finally, get yourself one of the IT bags of the season in the medium 'Stirrup' bag from Botkier. The gold leather version is $610, but luckily the ever-reliable ASOS have come up with a bargain alternative. And when I say bargain, I mean it. Their gold zip detail bag might not be quite as swish as the real thing, but it's only £10, and who can argue at that price? Both bags are also available in a subtler metallic bronze if you don't like the sweet-wrapper shiny gold.
