High-street fashion has had its up and downs to be sure. But over the last decade or so the big brands have realised that to connect with the modern-day shopper, they need to come up with something that evokes aspects of high-fashion but can still be bought by someone who doesn't own a yacht.

Below we take a look at some of the best designer/high street collaborations, what their collections consisted of and how the designers have helped boost some high-street names to unprecedented levels of success.

Kate Moss for Topshop

Okay you got me, Mossy is not a designer...but her 2007 collection with Topshop was a momentous step for high-street fashion. With queues snaking along Oxford Street on opening day, the collection consisted of key pieces inspired by Kate's signature style. With fourteen collections so far to date, this pairing has perhaps been one of the most commercially successful collaborations, earning Moss a reputation as a successful businesswoman. Other notable collections to grace Tophop's shelves are JW Anderson's S/S '13 line that demonstrated a more sedate selection of shapes and styles. His second collection modernised classic items such as knitted jumpers in bold patterns and trench coats and bomber jackets with a sleek patent finish.

Jil Sander for Uniqlo

Getting back into the game after taking a design hiatus for five years, Jil Sander's J+ range for Uniqlo was a stroke of genius. Teaming the functional, ready to wear style that is the Uniqlo brand, with a designer renowned for minimalist design and modern tailoring meant that Jil's five collections for the Japanese brand were a favourite with male and female office workers everywhere. The final collection featured key pieces in muted winter colours such as single and double breasted wool coats and ribbed polo necks.

Hermes meets Vans

In a clash of cultures, luxury met the original skate shoe in a slightly off the books collaboration. Celebrity stylist Robert Verdi reached out to the brand asking them to design a custom series of the classic slip-ons inspired by his favourite Hermes scarves. With designs ranging from lavish gold chains, to florals, to slightly creepy wind-up figurines, these are not shoes you'll be landing an ollie in any time soon, as they cost anywhere between $200-500!

Paul Smith for Barbour

In 2012 the king of zany lining teamed up with fellow British fashion staple, Barbour, to give it a playful twist. The brand, who have already made a conscious effort to appeal to a more modern set of customers by teaming with designers such as Alice Termperley and Anya Hindmarch, have kept to their traditional 'heritage' roots but using Sir Paul's signature design style to ensure the wax jacket continues to be a fashion staple.

Everyone for H&M

The Swedish high-street giant has had some pretty incredible collaborations over the years, Versace, Lanvin, Jimmy Choo...and more recently Isabel Marant. But it has to be the brand's first high-end collaboration in 2004 with Monsieur Karl Lagerfeld that warrants a mention. If shoppers were agile and cut-throat enough to make it through the throngs of people trying to get a piece of the collection, they were walking away with a Lagerfeld silhouette t-shirt, wool cashmere coats, and lace dresses. Sadly the partnership between designer and brand did not last as Karl felt H&M were too limited in their release of his range, meaning that most shops sold out much quicker than anticipated. Karl told What Wear Daily, "I'm sorry for the clients because I like the idea that everyone could wear Lagerfeld."

Prabal Gurung for J Crew

As one of the runners up of the 2010 CFDA/ Vogue Fashion Fund, rising star designer Prabal Gurung got to produce a capsule collection with J. Crew. The six-piece collection was launched online and as his reputation as a designer has exploded in the last few years it seems ridiculous to think of him as a runner up at all. The collection was dense in bows and ruffles, creating a feminine aesthetic throughout. More recently, Prabal has been cultivating his high-street design influence even further by collaborating with U.S retailer, Target for a 2013 collection. Overall, this was a more youth-oriented collection, featuring bright colours and less conservative shapes.
