TikTok’s social commerce platform, TikTok Shop, is introducing a secondhand luxury category in the UK, mirroring its successful US counterpart and competing with established players like The RealReal and Vestiaire Collective. The new category offers pre-owned high-end fashion items accessible within the TikTok app, featuring initial partnerships with five UK brands. Despite TikTok Shop’s substantial sales success, criticisms persist regarding counterfeit and low-quality products.
