What is the perfect school bag?

My first ever school bag that I recall was a blue brief case style canvas bag with a velcro seal, little handle and my school (Leicester High School for girls)' symbol. From this I moved onto a plain black rucksack (school rules), but as I grew older I became more and more rebellious with colour schemes until in about year 8 I ended up with a pink flowered Roxy rucksack which I thought was the coolest thing ever; looking back on it, it probably wasn't all the cool.

Bags have always been a very big part of my life as I believe a good bag makes the final cut to your outfit. If the bag isn't right, then the outfit isn't looking that hot either. However, even though I own a wide selection I am very picky and like them to be a little different. The most expensive bag I ever bought was a bag I found at Burghley Horse Trials on one of the stalls. It is made out of old recycled metal such as car parts, bottles caps etc with the song words 'I get a kick out of champagne' surrounding champagne glasses with the bubbles made out of Swarovski crystals. Another bag of mine that I love is a Paparazzi clutch with the magazine cover on an issue of gardening with the words 'English Rose' in italics. A bag I use on all my nights out, no matter what I’m wearing or where I am going is a giant leopard print clutch from River Island (been known to fit a bottle of wine in there). I love it because it is big enough to fit all my junk in cigarettes, lighter, camera, phones, makeup, money, keys etc but also has three ways of carrying it; under the shoulder, handle and chain.

Today after arriving at FBI I realised I needed a bag other than the free FBI bag that was given to me as even though it is big and sturdy I need something a little more stylish and something that screams fashion and who I am.
So after my course I went to the bag shop in Bondi Junction and instantly fell in love with and purchased a blue quilted limited edition Guess bag.
Hopefully it will show my sense of fashion taste and flair.

So what's your first memory of a school bag and what's your fave bag?
