STYX

STYX was founded in 2024 and is based in Porto, Portugal. STYX offers a selection of designer and vintage clothing, footwear and accessories. All items are carefully curated, checked for authenticity and condition. We believe in the sustainable potential of fashion by carefully considering our relationship with clothes. Each piece is individually sourced and thoughtfully selected from across the globe. 

In June 2025 STYX has opened its store in Porto.

At STYX authenticity is at the forefront of our mind when sourcing our items. Authenticity cards, dust bags will be provided where possible. We completely understand the uncertainty around purchasing second hand designer pieces. We have been sourcing and re-selling for 5 years and we would never list an item we don't deem authentic. If there is an item you're concerned about, we'd be happy to point out the aspects of the item that tell us it is authentic.

Store location: Rua do Heroísmo 14, 4300-252 Porto (3 min walking from Campanhã train station/ nearest metro stations: Heroísmo and Campanhã).
