A swimsuit is obligatory
Even if some Germans like to swim naked in lakes, it's prohibited in public pools. You can't jump into the water in your underwear either — it needs to be a proper swimsuit. As for the burkini, since it's made out of swimsuit material, it's a legal option for Muslim women. However, that doesn't protect burkini wearers from racist comments. Every year, local attempts to ban it also make headlines.
