In many cases, cosplayers like to take a store-bought outfits and embellish it with their own style to make a unique representation of the character. As an added bonus, the costume also comes with a metal pendant just like the one Geralt wears on the TV show, as well as a chain. Lastly, you’ll want to have a medieval two-handed sword, and while there are plenty of models to be bought online, you’ll want one that looks as much as the one on the show, so try to avoid decorative swords that have curved blades, serrations, or anything else of the sorts.
