Cheap winter clothes - Where to buy in Stuttgart?

All large clothing stores will sell winter coats of course. It really depends on what you want. Some people like a sporting style like they would wear for skiing or winter sports so they go to a sporting goods place. But there are lots of general clothing stores. C&A is cheap but has reasonable quality. Primark even cheaper but I think have lower quality, TK Maxx has strongly cut or fashioned cloths and some are very cheap and others expensive. Breuninger tends to have better quality than the others mentioned but is significantly more expensive. Another large shop in the Königstr. is Karstadt Sports. They usually have a good variety with medium to high medium prices.

Second hand clothes shops tend to be at obscure locations in the suburbs (cheaper rent!) and finding reasonable clothes and fitting sizes is a hit and miss affair. Google „Sozialkaufhaus“ for the ones run by charities if you want to support recycling, jobs for the disabled and use of the proceeds for good causes!
