Secondella is one of the best vintage and secondhand stores there is, if you are after high-end design brands. They carry clothes and accessories from all top brands such Gucci, Prada, Chanel, Dior etc. The store is over 300 square metres and is a joy to hang around in, even though some of the stuff there still might be too expensive for one’s wallet.
Edit: I can’t turn off the autostart of the Secondella video, so instead of embedding a video with autoplay, here’s the direct link to it instead.
It’s located on Hohe Bleichen 5 in Hamburg
