With the recent launch of the Julien MacDonald for Comet collection, it's got us thinking about other big fashion collaborations that have taken place over the year. 2010 has been a time of some of the greats teaming up, and we've come up with our top five most exciting...

First, it has to be the new Julien MacDonald for Comet designs. Butterflies on Babyliss hair straighteners or a hairdryer couldn't be more perfect to us. After all, we want those hard-working appliances to look pretty too, right?

You can get the straighteners for £29.99 and the hairdryer for £24.99, both from Comet.

With Carrie Bradshaw swapping her MacBook for a HP laptop in Sex and the City 2, Vivienne Tam's colourful laptops became all the rage.

So much so, in fact, that they even appeared in the hands of models on the runway. This particular butterfly laptop appeared in Abu Dhabi with our four favourite girls, and while it's not clear which of them it belongs to, we're made absolutely positive that it's the perfect piece of technology for fashionistas on the go.

When H&M were set to reveal who their latest designer collaboration would be with, fashionistas were sent into a frenzy as YouTube videos hit the Internet, giving subtle clues over who the chosen one would be.

Soo enough, we knew it would be Lanvin, and last month all the die-hard fans hoping to get some cut-price designs from the French fashion house were queueing overnight in the streets. Now it's here, there are bright colours, LBD's, ruffles and structure galore, making this one of the most talked about designer collaborations of the year.

To be honest, we aren't massive fans of Uggs. But we have to say, when we heard that these sheepskin, over-exposed boots were teaming up with ultra glam Jimmy Choo, we thought the idea was totally inspired! If not a bit of an eyesore.

These embellished Uggs are must-haves for every collector who owns short, tall, chestnut, black, and a whole host of the boots. But they don't come in cheap. You're looking at prices from £700 upwards. Yes, really.

How sad. 2010's designer collaborations also saw the last ever collection from Kate Moss for Topshop. But she certainly didn't disappoint, and managed to go out with a bang!

As well as some new must-haves out on the shelves, she brought back some of her best designs from over the years. Which means we can once again get our hands on the iconic pansy dress from her first collection.
