Use filters Be specific in searches. “If you enter ‘green dress’ into the search box on eBay, it will bring back thousands of results, so use the filter,” says Becky Barnes, a sustainable stylist from Bristol, who has been buying exclusively pre-owned clothes since 2017. “You can usually select brand, fabric, length, size – the filtering is more sophisticated than on Vinted.” There are brand new items for sale, too – if you only want pre-owned clothes, select “used”. Ash Meyer, 19, a student living in Sheffield, is a regular shopper on Depop, buying basics such as joggers and T-shirts as well as “statement pieces, such as vintage football shirts and a 90s Coogi jumper”. The site has 34m items for sale and an average of more than 180,000 new listings every day. Meyer sets a price cap on his filters to avoid being tempted by more expensive items. If he’s given himself a budget of £25, he starts looking for lower-priced items first. “I’ll start at £20 and if I can’t find what I’m looking for, I’ll go up to £25. It stops me going over budget. If I find something I like, but it’s too expensive, I set an alert so that the app tells me when similar items come up for sale,” Meyer says. Monica Buchan-Ng, head of knowledge exchange at the Centre for Sustainable Fashion, based at London College of Fashion, has a one-in, one-out policy for clothes in her own wardrobe, so new purchases are carefully chosen. She advises a targeted approach. “Know the brands you like and how you fit and look in them. Go to their stores, try on a few things, see what size fits you,” she says. “It can be useful to have a portfolio of brands you are interested in. I’m a huge fan of Jaeger and I know what size fits me, so I keep an eye out. Maybe you like Dries Van Noten from a certain era. Set alerts so that you only see relevant listings.” Train the algorithms When browsing, click “like” on any items that appeal. Sanna Moktadir, a 20-year-old student also based in Sheffield, says: “The more pieces you ‘like’, even if you’re not going to buy them, the more the apps will recommend things that are your style, so you have more chance of finding what you want without having to spend ages looking.” Shop out of season “I recommend shopping out of season to beat the crowds and get the best price,” says Kirsty Keoghan, the global general manager of fashion at eBay. For example, look for your dream wool coat in the height of summer. Barnes says: “That’s where you’re going to save the most money; if nobody’s after that piece and there’s no demand for it, you can perhaps drive down the price.” Ask questions Ask the seller plenty of questions before buying. “Ask for a close up of the label and care instructions; you don’t want dry clean only if you never dry clean clothes,” says Buchan-Ng. “Ask to see areas that are often worn or stained, such as under arms, or inside collars for shirts, or the soles of shoes. I ask a lot of annoying questions. Sometimes people ignore me, but if they do I just move on.” Barnes asks sellers to provide their own measurements so she can see if they have a similar body shape. “I’ve found that probably eight out of 10 sellers are prepared to provide that for me. There are some who just refuse, and maybe they don’t have a tape measure or can’t be bothered. But I won’t take a risk on it now, because when I have had disappointments, it has mostly been down to sizing.” Make an offer Barnes says: “Particularly if something has been on sale for a while, people often will say yes to a lower offer, because they just want to get rid of it.” Vinted, Depop and eBay (for some items) let you click a button to make an offer. Depop offers that are not accepted within 24 hours automatically expire. Vinted caps discounts at 40% off the listed price. Postage isn’t subject to discount. Competition can be tough for on-trend garments on eBay auctions, and Barnes warns buyers to beware of “sniper” bids. That’s where you make a bid, and for ages it looks like the item is yours. Then just a few seconds before the end of the auction, a higher bidder sweeps in and takes the prize. “One strategy to lessen the anxiety is to select the highest amount you’re prepared to bid up to; eBay will then automatically bid on your behalf up until that maximum.” Check sellers’ credentials Whatever the platform, find out what you can about the seller. “Look at what else they are selling, their feedback, reviews, ratings. I’m always looking to make sure this is someone who is trustworthy,” says Barnes. She is put off by negative reviews, or sellers who have been inactive for a long time. Buy bundles Creating a “bundle” of pieces from one person can bring savings on postage, and the seller may offer a discount, too. Vinted and Depop make this straightforward – go to the seller’s shop page, add the garments you like to the bundle, then buy everything in one transaction. Learn basic sewing skills “Build up basic sewing skills like hemming or adjusting a waist band,” says Buchan-Ng. “Then if something arrives and it’s not quite right, you can adjust it and make it work for you.” Maybe you love the fabric a dress is made from, but the cut is wrong or it’s too long, or you’ve found the perfect bag for next to nothing, but it needs some patching up; you could create something new that suits you. Beware of counterfeits If you’re buying designer items, do your research. May Berthelot, the anti-counterfeit director at Vinted, says: “Ask for proof of authenticity; this can include a receipt or certificate of authenticity. Ask for photo closeups of details such as the logo, stitching lines, packaging and dust bag, serial number, hardware (zips, clasps etc) and label, to check that they are of high quality.” Compare details with images on official websites. Some platforms offer verification services. Vinted charges buyers £10 to check items costing more than £100, as long as its on its list of designer brands. There is a diamond badge next to eligible items, and the buyer can select the verification option at the checkout. The seller then sends the item off to be checked, and if it passes it is sent to the buyer. If it fails, the buyer is refunded for the cost of the item and the verification fee. Platforms specialising in high-end items, such as Vestiaire Collective and Reluxe, have a list of accepted brands and offer dedicated authentication services, too. Watch out for fees Expect to pay postage costs, but there might be other fees, too. Vinted charges a “buyer protection” fee, of between 3% and 8% of the pre-postage price on each sale, plus between 30p and 80p. Depop’s Marketplace fee costs buyers about 5% plus £1. Both platforms say they refund buyers for items that are don’t arrive, arrive damaged, or are significantly not as described. EBay doesn’t charge buyers (or private sellers), and Keoghan says buyers are “protected by our money back guarantee and expert customer service team, at no additional cost. If an item arrives and it isn’t as described, buyers can contact our customer service team where we’ll work to find a solution within 48 hours.”
