Gucci Sylvie handbag, £723, Vestiaire Collective
How it works: The authenticity team are trained counterfeit experts who check the item is everything you've said it is, including size, shape, colour and description, so ensure you're precise, accurate and honest. Upload a snap and description either online or via the mobile app. Your item goes online once it's been approved. When it sells, send it to the Vestiaire Collective HQ in France using the prepaid shipping label provided. The company will then check the item and send it on to the buyer so you can get paid.
What you should sell: Celine, Louis Vuitton, Hermès and Chanel bags, particularly rare ones, sell really well, as do fashion insider-y brands such as Jacquemus and Cult Gaia. The fastest selling item was an Hermès Birkin bag which sold in 17 seconds for £42,000, and the weirdest upload was a Mercedes Benz car.
When you should sell: 3,500 new items are submitted daily, and Sunday is when the most items are uploaded to the site, but even so, the best time for your item to go live on the site is a Tuesday as this is its busiest day - particularly lunchtime and early evening.
The go-to site for last-minute bargains, eBay is known for its competitive users - the auction-style platform creates suspense and attracts shoppers hoping to nab an amazing piece at a low price.
How it works: The onus is on you to take photos of your piece, write a title, description and ship it to its new home. Sellers typically do an auction-style listing starting at a low price to attract buyers, in the hope that they'll outbid each other in the hopes of winning the item. You can also provide a higher 'buy it now' price, which ceases the auction if a buyer is prepared to pay it.
What you should sell: Coach, Missoni and Valentino sell really well, but the beauty of eBay is that you can sell anything, be it Sweaty Betty activewear or a coat from H&M. Think carefully about how you list a designer item though, as it's hard to prove it's genuine without a receipt, packaging or authenticity card. If a seller has every size of Giuseppe Zanotti boots for £90 (RRP £1,200) it's probably too good to be true.
When you should sell: Sunday is the busiest day for eBay, particularly via the app, so aim to list auction-style items to end on a Sunday afternoon/evening as people are more likely to be free to bid.
Depop bills itself as "the creative community's mobile marketplace." It looks like a hybrid between eBay and Instagram and is fast becoming millienials' go-to platform for buying and selling designer, high street and vintage fashion.
How it works: Depop is best navigated via the app. Users can set up a Depop store with all of their items for sale. Buyers follow their favourite sellers, who are as likely to be celebrities and influencers as they are regular people.
It's up to you to do all the work here, but the upload process is simple: take a few snaps of the item, write a description, add a few relevant hashtags and publish. Buyers can message you directly with questions and price offers, or just hit the 'buy' button.
What you should sell: High street and vintage clothes dominate the site, with a smattering of streetwear too. That Zara party dress you only wore once, or the limited-edition Nike trainers that are half a size too small, will fly on Depop.
When you should sell: Anytime! Once your item is online, it's searchable by buyers all over the world. If it lingers on the site a long time though, you may have priced it too high so consider reducing it.
London-based Hardly Ever Worn It is a luxury marketplace for new and used designer ladies, mens and kidswear, and has an ever-growing male community; in 2013, the site had 20 male members, at the end of 2015, this had gone up to 4,000. It's easy to get addicted to the site, searching for that navy Mulberry tote you've had your eye on - over 55 percent of traffic to the site is returning customers.
How it works: List your item for free on the site (as soon as the Hardly Ever Worn It team approve it, it goes live within a few hours); once it's sold, payment is held until the buyer has received their purchase. Once they confirm receipt, you're paid.
What you should sell: Classics such as Mulberry Bayswater bags, Chanel handbags, Prada totes and Christian Louboutin pumps are all highly sought after on the site, with Tom Ford most popular among the male buyers. Less well-known brands, even if they are exquisite, won't sell as quickly.
When you should sell: Mondays and Thursdays are when its users are most likely to buy. The site has a particularly long dwell time of six minutes for the average user, so be sure to include lots of images and a detailed description to make the most of it. If an item is desirable, classic and well-priced, it can sell within 10 minutes - if you decide to sell an unworn purchase, get it up as soon as possible so it's relevant and will be in demand.
Rebelle makes second hand selling and buying luxurious, with its 48-hour guaranteed delivery service, chic mint green packaging and high quality stock. The site has an average of 80,000 unique visitors each month, so you can be sure your piece will get the attention it deserves - a crucial factor.
How it works: Once you've listed your item, send it to Rebelle for free - the team then verifies its quality and authenticity; once it's been sold, it will be sent on to the buyer. You get paid once the item's been received. As the majority of stock is held at its site in Hamburg, it can guarantee a 48-hour delivery to the buyer.
What you should sell: Rebelle reports that bags by Louis Vuitton, Prada, Hermès and Chanel (the latter's bags sell in seconds) are its best sellers. Celine and Gucci also sell well. Small or local brands with niche products can take months to sell, particularly if it happens to be clothing or shoes in very small or very large sizes.
When you should sell: Thursday is the best day to upload on Rebelle - it takes 24 hours for each item to appear on the site, so will go live on Friday - just in time for bored browsers over the weekend. Rebelle buyers are more likely to buy winter clothes in colder months, and summer clothes in warmer months, rather than buying ahead for the next season.
With its mission to make second-hand buying the number one choice worldwide, Vinted is on the right track with its over 11 million members, nicknamed 'Vinties'. It's super easy to navigate, so it's no surprise that an item is sold every 49 seconds.
How it works: If you're familiar with Depop and eBbay, you'll find Vinted easy to use. It's up to you to list your item, set a price and post it to the seller. If a Vintie thinks you've overpriced your item, they can message you and ask if the price is up for negotiation.
What you should sell: Good quality pieces by Michael Kors, All Saints, Zara and Topshop all sell well on Vinted. Vinties like current season stock that's sold out in shops, so past season, unless limited edition or highly sought after, tends to take longer to sell.
When should you sell: The site is so popular that an active member in the UK makes a purchase every 42 minutes so you needn't worry about the best time to upload your items. This week, Vinted added the Netherlands, Italy and Spain to its already expansive user reach covering the UK, USA, Germany and Austria among others.
For luxury items, Vide Dressing meticulously checks the authenticity of each piece before it is allowed online. Once it's been confirmed as an original, sellers are all set to go. This gives added reassurance to buyers so they're more likely to splash the cash.
How it works: Once your item has passed the authenticity test, a buyer can order it by putting it in their basket and agreeing to pay for it. The seller then has 72 hours to confirm availability of the item (handy if you have also listed it on another resale site) and once confirmed, you ship the item to its new owner within 72 hours or the order is automatically cancelled.
What you should sell: Chanel bags, (in particular, the Timeless) Celine bags, Isabel Marant shoes, and classic Christian Louboutin Pigalles. Limited edition pieces from big fashion houses are very successful too - the more fine, rare and luxurious, the better. The most expensive item sold on the site was a Chanel watch at £38,000, so you know where to upload it if you have one lying around.
When you should sell: Pick a Friday evening at the beginning of the month to upload to Vide Dressing; it gets most hits over the weekend so will give your items the best chance of attracting a new home.
Sellers needn't wait for their items to sell on Edit Second Hand - it's the only resale site to purchase items directly from you, essentially becoming the buyer and taking the pressure off you to sell. The Edit team turn away on average four times what they are offered - this means the site is expertly curated to include only current and high quality items. It currently has 3,000 users each month, a figure on the rise, and buyers don't have to sign up to shop.
Ghost dress, £120, Edit Second Hand
How it works: Send Edit Second Hand a description of what you'd like to sell and they get back to you with a price they're willing to pay for it. Once you've agreed on a sum, send your item to be verified and they pay you within 48 hours - as easy as it gets.
What you should sell: Isabel Marant, Iro, Chanel and Helmut Lang are the best-selling labels. High street brands don't work for the site (the only one they buy is Whistles) as they aren't what this customer is looking for. Unlike most resale sites, Edit Second Hand also offers returns if the buyer isn't satisfied.
When you should sell: As Edit Second Hand buys each item, expect it to go live on a Wednesday or Friday. Its average selling time is four days, but many items sell before they hit the site as they have a customer waiting list - sign up to its newsletter to hear about the good stuff first.
As the name suggests, High Fashion Society only allow uploads from luxury brands that it believes will sell, saving you months of waiting for your piece to be bought. The site also receives celebrity donations from the likes of Sienna Miller, who has used it to raise money for children's charities.
Celine Trapeze tri-colour bag, £1,600, High Fashion Society
How it works: After completing a consignment form for the pieces you'd like to sell, High Fashion Society gets back to you within 48 hours with an approval and estimated selling price, helping you to price fairly. Next, arrange a collection for your goods to be sent to its London office on South Molton Street where the pieces are checked and professionally photographed. The rest is taken care of by the team and your item is sent on to its new home. You're paid once it's been received.
What you should sell: Mulberry, Christian Louboutin, Louis Vuitton, Hermès and those ever popular Chanel bags are the site's best-sellers.
When you should sell: Wednesday is the best time of the week for new arrivals as people are often shopping for something to wear at the weekend. The last week of the month is usually the busiest time for buyers as it's payday week for most.
Collector Square was launched in 2013 by the founder of the Artcurial auction house, Nicolas Orlowski, and digital entrepreneur, Loïc Bocher. It has since become a global go-to for pre-owned luxury bags, watches and jewellery online. The showroom is in Paris, but over 50 percent of sales are from outside of France. Featured brands include Chanel, Hermès, Cartier and Rolex.
How it works: Collector Square take care of everything for you, from collection, expert appraisal, photos, description and online upload, through to selling and shipment. They also insure and take responsibility for each consigned item, from the point of collection at the seller’s address right through to the buyer receiving the item in person or via a delivery service.
To propose an item for sale you can either complete an online valuation request or (if you do happen to be passing through Paris) drop into the showroom, which is open Monday to Saturday, 11am to 7pm (36 boulevard Raspail 75007 Paris).
What you should sell: The best selling jewellery brands are Cartier and Hermès, while Pomellato has done particularly well this Christmas. For watches, Hermès, Cartier and Rolex are the front runners.
