What if you could get rewards towards future purchases, just by sharing what you have in your closet already? Zappos founder Nick Swinmurn has launched a new site to do just that. It’s called RNKD, and it wants you to show the world what kind of clothing and accessories you already own.

Even though the site launched last month and is still in beta, RNKD shared some extremely interesting stats with us that show a growing community for the premise. You might think that something like RNKD is just for the ladies, but the company tells us that 46% of users are male. They’re seeing some eye-popping engagement too, with users sharing 26 items each on average.

The idea is pretty brilliant when you think about it, if people share the items that they already have, then the site will known exactly what brands to partner with and what deals to offer to its user base. RNKD says that 2,000 different brands have been uploaded to the site so far.

The most popular brands on the site are Nike, Ralph Lauren, Express, and H&M. With this type of data, RNKD can do some serious damage in the social shopping space.

Show me yours, I’ll show you mine

Just getting deals based on what you have already purchased is interesting enough, but being able to share the contents of your closets with others takes it to another level. Each user gets a profile, and that profile shows all of the items that they have uploaded.

You can search through the items by type, brand, or the store that they bought it from. One neat feature is a quick breakdown of items by category so if you were holiday shopping, you’d be able to see the gaps in your friends wardrobe.

You can upload your items on the site, or use RNKD’s iOS and Android apps.

Reward me!

Here’s where things get interesting on RNKD. The more you share, the more chances you have to win rewards. The rewards or none other than Zappos gift certificates. Makes sense, since RNKD’d creator is the founder. The site sets up fun little categories like “Most Improved” and “Best Watch Collection” and rewards its users with gift certificates to buy more stuff. Pretty genius. You can even get badges for the types of things you share, cementing your place as a top brand maven.

If you’re really into fashion, you can get lost for hours on this site. RNKD has done a really awesome job of making everything clickable and shareable, so you can share something from someone else’s closet on Facebook or Twitter.

We’re told that of the items uploaded, the average user shares 12 different brands & 9 different stores, so I have to imagine that partnerships with these big brands are coming soon. It’s the perfect audience to share deals and exclusives with, and since they’re showing what they have in their closet already, we know that they like to buy.

As we know, today is Cyber Monday in the U.S. That means that all of the people who aren’t crazy enough to have visited stores on Black Friday, can sit in the comfort of their own homes or offices and buy a lot of crap that they don’t need.

BeachMint wants to revamp a tried and true model, home shopping networks. You know, the channels that show attractive hosts hawking items for hours and hours on end, swearing to us that everything is in limited numbers, so you better hurry up and dial.

Randi Zuckerberg, having just left Facebook to start her social media agency R to Z Media, has teamed up with BeachMint to bring you an all-day “home shopping experience”, hosted on Facebook.

The live video segments will feature, beginning today at 10am PT, BeachMint partners and designers Mary-Kate Olsen and Ashley Olsen.

During the livestreamed telecast, you’ll be able to purchase the deals that the hosts are talking about, much like you would on the Home Shopping Network. However, a telephone isn’t required, thanks to the Internet.

BeachMint was founded by MySpace Co-Founder, Josh Berman, and Diego Berdakin. The company is launching small curated sites with designers such as Kate Bosworth, Jessica Simpson, and the Olsen Twins. It hopes that this approach can beat out the nameless and faceless daily deals style of sales that has become so hot these days.

Will you tune in and buy? I’ll be checking in to see how it all goes, as bringing known names together with fashion and technology is a brilliant play in my opinion.

If you’re shopping for gifts this holiday season, or enjoy limited edition fashion, one site has paired something you’re already doing, with something you should be doing. Giving money to charitable causes.

The site Community Collection hand-picks the top fashion designers and sells their goods, while pairing pairs each designer with a different charitable cause for social good. Money from each sale goes to the charity, and you get a great piece of limited edition designer fashion. Everyone wins.

Here’s how Community Collection describes itself:

By getting “must have” merchandise from fashion and accessory designers you love, you also give back through your personal retail purchases. 20% of every purchase you make on our site goes to the charity paired with that specific designer. But it doesn’t stop there – we are committed to working with the charities to report back to you where your dollars went and the impact of your 20%.

It’s better to give than receive

Since launching on October 18th, Community Collection has raised $3,142 benefitting 15 different charities. The charities include American Cancer Society, Best Friends Animal Society, College Access Plan, Flying Kites Global, and Girls Inc.

The premise is simple enough and extremely powerful, since you’re shown how much of your purchase will go to charity, and which charity will be benefited.

Along with charitable giving, the site brings you exclusive items from such designers as Lulu Frost, and gives us an opportunity to learn more about the designer since each one has their own favorite charity. For each collection, a fundraising goal is set up, and the 20 percent that goes to charity is shown with each item.

If you’re already surfing the web to buy gifts for loved ones this holiday season, or even treating yourself, why not raise some money for charity at the same time?

If you’re one of the many carrying around a Square device to process payments or get money back from your friends after a night out at the bar, you may be interested in The Square Pouch.

Jack Dorsey, CEO and founder of Square, tweeted out the link to the Square Pouch last night.

While endorsed by Dorsey, the Square Pouch doesn’t seem to be created by anyone at the company Square.

After clicking through, the site explains exactly why you should both keep your Square safe and make it look pretty with its pouch:

Keep your Square dirt and lint free! Unlike others, the Square Pouch keeps your Square fully protected with its new design.

The company has even posted a video about how to use its Square Pouch:

Apple products are notorious for making people obsessed with accessories such as iPhone cases and iPad stands, so it’s only fitting that Square would get the same treatment. The Square Pouch starts at $7.99, and is available in black, white, red, pink, and blue.

How many devices in the Apple Store are under $10 and do so much? Not many. You might as well protect your Square in style.

Spanish startup Chicisimo launched last year as a community for fashionistas to share photos of their favourite clothes, tagging them with data about the brands, items and colours being worn.

Similar to Fashiolista (our previous coverage here), a community of fashion-obsessives has built up around the site, voting and commenting on each others’ looks. While there are obvious benefits for helping to push retail sales here, what’s really interesting is the data that can be extracted from the service. Chicisimo recently published a Street Fashion Report that shows how the service could offer Last.fm-like data to the fashion industry.

The data that Chicisimo can drill into is impressive. Top high street brands (Zara and H&M were runaway leaders of the pack here), top luxury brands (Chanel won on this front), most popular colours (black) and best of all – data about current trends in clothes. The startup’s analysis showed that the colour red, vests and long skirts have all increased in popularity amongst photos shared by users on the site in recent weeks.

At present, the dataset Chicisimo is working with is currently quite small. The data for Chicisimo’s report was gathered from 30,000 looks shared by 6 000 users between July 2010 and February 10th 2011. As such, the report can’t be taken as a guide to wider tastes, but as the service knows its userbase (all female, mainly under 35) it will become increasingly valuable as the service expands.

At the moment the data is a nice talking point and some prime fodder for a press release, but if Chicisimo is able to make this information update in real-time like Last.fm, it could actually be a great way of measuring young women’s clothing taste. Offer even more granular data at a price, and I’m sure the fashion industry would be very interested in paying for it.

Chicisimo launched German and Polish versions of its site this week, in addition to the existing English, Italian, French and Spanish offerings.
