The one mistake stopping people finding the best charity shop clothes
One mistake blocking charity shop treasure finds

Millie Bull has been exploring charity shops for as long as she can remember. The Deputy Editor of Spare Time says the most common mistake preventing people from finding the best pieces is only searching within their usual clothing size. Limiting yourself to one or two sizes means you could be missing out on dozens of great finds.

Don't shop by size

Bull advises starting at one end of the rail and methodically checking every item. Vintage clothes often run small, so it is worth considering larger sizes. Sizing also varies dramatically between brands – some run much smaller, while others are more generous. Personally, she sizes up for Zara and down for Tu, Primark, or F&F.

Think about the fit you want. Do you prefer a skin-tight T-shirt or a looser, oversized look? If you are after the latter, do not hesitate to try larger sizes – or even browse the men's section. While making smaller items bigger is tricky, oversized garments can often be tailored for a perfect fit.

The men's section is often a hidden gem for women. A few years ago, Bull picked up a men's medium Patagonia fleece from a local charity shop for just £8, though these retail for around £90. Though slightly oversized, it has become one of the warmest and most comfortable jumpers she owns. Men's shirts – especially linen – are perfect for throwing over a vest top on warm summer days.

Designer finds and checking labels

Shopping for secondhand designer items can be a minefield. Many charity shops have a 'designer' section featuring brands like Whistles, Mint Velvet, AllSaints, Levi's, Rixo, and Ralph Lauren. Bull loves the thrill of uncovering a designer bargain, but getting the right fit is often tricky – luxury brands usually run smaller, so she tends to size up. If you are really unsure, most charity shops have a changing room where you can try items on, and if they do not, they offer a flexible returns window, provided you keep the original receipt and label on the garment.

Before buying – especially if it is vintage – always check the label to see what it is made of. This often helps decide whether to make a purchase. Is it easy to wash? Will it hold up well? Will it become bobbly or lose its shape? These are important questions to ask before you commit. When it comes to jumpers, a jumper made mostly of wool will likely last longer, keep you warmer yet breathable, and will not need washing as frequently as synthetic knits.

Checking the label also helps judge value for money. Natural fibres like wool, silk, linen, and cotton are more durable than synthetics. Sometimes, tags are removed before donation to prevent returns, so reading the label can reveal whether you have found high-street, fast-fashion, or designer pieces.

Where are the best charity shops?

Bull is lucky to have plenty of high-quality charity shops nearby, but the very best finds are often in affluent areas. On a visit to Chelsea, London, she was amazed by the sheer number of designer items on offer in the local charity shops. Other upmarket London areas, such as Marylebone and Primrose Hill, also boast fantastic charity shops brimming with designer donations.

If you are not near London, consider exploring the more 'posh' areas nearby. Towns like Tunbridge Wells, Winchester, Chichester, Bath, Marlborough, and Cambridge – known for their affluent demographics – are usually treasure troves for quality finds. Larger cities with big student populations are great for hunting the latest trends without spending a fortune on fast fashion, and cities also tend to offer a wider variety of vintage and eclectic pieces.
