I've lost weight over the summer, so needed quite a few clothes for autumn/winter, and also spruced up 3 bedrooms so bought curtains and cushions ect from there as well.
I've been very happy with my purchases. I've only bought clothes that say very good or new condition, from sellers with good reviews, and brands that I am familiar with and know are reasonable quality.
I've pretty much replaced my all my winter clothes, including coats and boots, for about £150. No way would I have been able to afford to do this without Vinted and Ebay. All the bedrooms have new (some new to me, some actually unused) curtains, bedding and cushions. For under £200.
The only issue I have had is with the delivery service, and it did turn up eventually. The sellers have all been fine. I've not sold anything yet.
Edited to add I am very much in the jeans, t-shirts, jumpers and dog walking coats camp. I am retired and my lifestyle has never needed expensive designer gear. Also I am probably in the frumpy category, because I like Brakeburn, Fatface and Seasalt, and love a stripey Breton.
