Most women dream of owning a designer handbag, but seeing as most of them cost the equivalent of a month's rent it usually stays just a dream. However, what if I said buying said bag also means that you'd be doing something for a charitable cause...

British fashion model Erin O'Connor is leading the celebrity support of Save the Children's Christmas 'Bag to Save a Life' appeal when it launches tomorrow, Friday 25th November 2011. Erin is joined by other well-known names such as Sienna Miller, Tilda Swinton, Florence Welch, Gemma Arterton, Georgia May Jagger, Annie Lennox and the UK's Prime Minister's wife and Save the Children Ambassador, Samantha Cameron to raise funds for the charity's lifesaving work in the poorest countries.

If you fancy snapping up a bag by the likes of Christian Louboutin, Mulberry, Jimmy Choo, Miu Miu, Prada and many more - donated or designed by the lovely celeb ladies previously mentioned - make sure you join in on the online auction from tomorrow on www.savethechildren.org.uk/bagtosave.

Samantha Cameron has donated her Jimmy Choo bag, Sienna Miller a Miu Miu, Tilda Swinton has donated a bag from Chanel AND a bag from Victor & Rolf, while Gemma Arterton has donated a leather patent Prada bag.

Save the Children ambassador Samantha Cameron said: "I am delighted to donate one of my handbags to Save the Children's Bag to Save a Life auction. It a great cause and the proceeds will help provide more health workers around the world who in turn will stop the needless deaths of children. Please get involved and do your bit to help save a child's life."

Tilda Swinton said: "Bid high! Bid so much higher than you think you will or can! Think of a dicey number and double it. And then double that. No fancy bag can ever carry what your generosity will mean to the children it will help to live. Make this beautiful object truly valuable by investing real money in real life - and carry the evidence with pride. Don't count the cost. Think of it as paying something back for all there is to be grateful for in your days."

If you want to take part in the auction, the starting price will be at around a quarter of the bags' recommended retail price. You can also donate any unwanted bags you might have laying around at any of the Save the Children stores around the UK to be included into the auction.

The online auction will be live from Friday 25th November to Sunday 4th December 2011.

Getting Christmas presents for girls can be easy, just head to the nearest beauty section and you'll be safe. But if you're looking to get something a bit more unique - and not to mention - eco-friendly, then you've come to the right place. I've waded through the froth to find some of the more desirable and sustainable presents for her out there. If organic knitwear, limited handmade pieces and fairtrade scarves are her things, look no further!

I love the playfulness and British eccentricity of Lu Flux's designs. A myriad of colours and a couple of pineapples, the A Lu Ha Spring Summer 2012 collection has definitely been inspired by the island of Hawaii (the name gives it away really...)

Lu Flux debuted at London Fashion Week as part of Vauxhall Fashion Scout's 'Ones to Watch' show in 2009, and has after exhibiting under the Estethica initiative at Somerset House for two seasons been awarded the Innovation Award which celebrates her inventive and exciting designs in the world of sustainable fashion.

We've previously written about 'reverse graffiti' and 'living billboards', and we're familiar with 'guerilla gardening' and 'knit graffiti' but have you heard of moss graffiti? The latest in street art projects aiming to enrich derelict urban spaces is cleverly named Mossenger and is the brainchild of London-based artist Anna Garforth.

Anna's project uses biodegradable ingredients to attach moss letters to walls to spell out poems. How wonderful isn't that? The poem you can see on these pictures are by Eleanor Stevens and will be featured in four parts - each sentence is to be displayed somewhere in London.

Have you spotted any other green street art projects where you live?
If you see Anna's work when you're out and about in London tweet us @Hippyshopper as we'd love to see more!

With predictions of Arctic winter conditions looming, Britons will not be happy with the news that energy costs won't get slashed just yet - and may continue to increase in the future.

Prices are set to continue to rise because of the rising cost of gas on the international market, and now Prime Minister David Cameron has admitted the Government need to work "harder and faster" to bring down energy bills ahead of a summit being held at Downing Street today, Monday 17th October 2011, to discuss the hostile energy market in Britain.

Following the latest Ofgem report, David Cameron has in a joint article with Energy Secretary Chris Huhne on moneysavingexpert.com outlined what the Government are looking to do: "Energy bills have increased by more than £100 for most people since this summer (the cost of gas and electricity has risen by up to 18% in the past few weeks). These price rises couldn't come at a worse time for consumers who are already feeling the pinch from rising petrol prices and the cost of the weekly shop."

Regulator Ofgem published plans last Friday in which it said suppliers will be forced to have no-frills tariffs - one standing charge plus a unit charge for energy used - to make it easier for consumers to figure out which supplier is best for them. But unfortunately this won't be put into motion until 2012 and while big energy providers like British Gas and Npower expected to pledge not to raise prices again this year, it can't be avoided that people will see their bills increase this winter.

But there are some things you can do to cut your energy bills, here are four tips:

Don't you dare to dust away those cobwebs - Halloween is almost here! At the end of the month it's time for trick-or-treating, scary costumes and sweets, lots and lots of sweets. A big business in America, this 'holiday' is catching on over here in England too but unfortunately can be one of the most wasteful times of the year. Just thinking about all those individually wrapped sweeties that get given out and the plastic decorations bought at the local pound shop only to be thrown out afterwards makes us feel bad. That said, we're not saying you shouldn't enjoy the festivities, so here are some tricks to have a greener Halloween.

I've recently become obsessed with lace; especially black lace. And with autumn bringing with her promises of cold evenings and glamorous events (one can but hope!), I am on the hunt for beautiful and durable, yet sustainable pieces that I can fill my wardrobe with.

The dark romantic feel of the Minna autumn/winter 2011 collection is perfect for the long wintery months ahead. Consisting of a series of pieces in hard wearing fabrics such as wool jersey mixed with reindeer leather and silk that have been hand dyed to create a vintage feel.

This is true Eco Luxe with each piece hand embellished and made from sustainable, organic, recycled and locally produced textiles.

My favourites are Marileen (£322), Pauline (£342) and Tilly (£311).

OK, so this particular skyscraper hasn't been built yet but the images we've seen of the Bionic Arch are very impressive.

Taichung in Taiwan is in dire need to reduce the city's carbon and as part of the 'Taichung Active Gateway City' Vincent Callebaut has put together a proposal that is an architectural gem - a green gem.

With its vertical gardens and living facades the Arch is almost like a vertical park, and will receive all of its electricity from bio, solar and wind energy sources. It will have zero emissions so will help towards achieving the city's carbon reduction plans.

To go with the Bionic Arch Callebaut has also proposed to create green living quarters nearby for sustainable urban communities to prosper in.

I love the Shard that is currently being built in London, but can we also get a Bionic Arch please?

Kelly Brook unveils her campaign for PETA targeting the exotic skins trade on the eve of London Fashion Week in Covent Garden, London.

The 31 year old model was shot with a snakeskin painted onto her body by singer Bryan Adams for the animal rights group in order to highlight the cruelty suffered by reptiles that are killed for their skin.

Brook says: "It makes my skin crawl to think about the violent ways snakes, lizards, alligators and other exotic creatures are raised and killed for boots, bags and belts."

The Edun Autumn Winter 2011 Menswear Collection uses layers and dimension to create a well-travelled feel that is juxtaposed with modern silhouettes.

Styles are made unique with added pockets, stitching and darting details. Sweaters and knits span the spectrum, from lightweight layering, to a fresh twist on vintage Fair Isles.

Washed wools, pilled cotton jersey, and distressed French Terry provide a variety of textures for a worn-in tee. Tops are oversized, elongated and deconstructed, consisting of slouchy oversized chunky knit sweaters and soft tailored jackets. Bottom silhouettes range from clean slim straight tailored pants to tapered leg drop crotch pants. Denim is workwear influenced; most of the denim is made from recycled fabrics in Africa and finished with organic washes.

Colours are inspired by natural elements and include stone and ash accented with petrol and ice. Red brick and cranberry wine play off sediment black, and dark neutrals like storm and tar are accented with raisin, mulberry and peacock.

I'd very much like my man to dress like the Edun man - actually come to think of it just give me the clothes AND the man!

Edun's Autumn Winter 2011 collection focuses on fashionable, utilitarian outerwear, particularly jackets and coats that combine leather and wool. Textured knitwear that has been made in Africa by nuns also took centre stage: dresses, cardigans, pullovers and skirts were seen on the catwalk in variations in the classic Fair Isle pattern.

In contrast to the more heavy winter wear were girly draped dresses and blouses in intense patterns and vivid colours.

Founded by Ali Hewson and Bono in 2005, Edun is a for-profit business with the aim of creating a global fashion brand, making beautiful clothing whilst committing to developing trade with Africa and encouraging others to do the same. Having already established itself as a cult brands, Edun is based on a belief that style should have substance and while it has always sourced globally, as its business grows so does its production and work in Africa.

Not that July has given Britain many sunny hours so far, but with the news of rising electricity prices many Brits are undoubtedly thinking about installing a solar panel or two on their roof to reduce their electricity consumption. A Suffolk company has gone a couple steps further though by installing 7,000 (!) solar panels.

The roof of Promens' warehouse in Beccles, Suffolk claims to be the UK's largest solar farm and will use almost 100% of the energy generated in the company's manufacturing process. Since the Government has dramatically reduced subsidies available for any solar scheme over 50KW after 1 August 2011, it is likely this is the largest roof-top installation we will ever see on the British Isles.

It is great to see that companies are doing more to make use of the great renewable energy source sunlight is and we hope more will follow. Developed by Lightsource, the 7,000 solar panels will give the site a capacity of 1.65MW.

With the summer looking to have skipped straight into autumn, and the heavens have opened above us this eco bikini by French label g=9.8 is the perfect way to look good while thinking about the environment. We're not sure about how to pronounce the name (gee-equals-nine-point-eight?) but these bikinis ensure you can be eco, sexy and sensual.

Made from recycled wood the fabric is, according to designer Sophie Young, as soft as silk with the feel of cashmere and coolness of linen. The material is also biodegradable and anti-bacterial - triple great!

If you don't want to be walking around in a bikini all day, there are lots of other fantastic eco-labels out there that can keep you stylish and eco-savvy.

Over the last couple of years, we've seen an increase in the high street brands introducing organic cottons and ethical fairtrade collections, and celebrities like Emma Watson have teamed up with labels to show that fashion can be fab and eco!

Festival season has begun! It's time for weeks and weeks of enjoying live music and chilling with your friends with an organic cider or three. Festivals also mean camping - unless you've booked yourself in at a local B&B - and having your usual beauty routine put on hold.

If you're heading off to Glastonbury next week or any of the other happenings this summer, we've gone searching for gadgets and clothes that let you enjoy the days while still being environmentally friendly.
