>>45192217If you complete a couple of matches of the Galarian Star Tournament, a man in a blue suit and hat will appear in Wyndon Stadium, (if you have ever suffered Martin's Solrock in Max Raid dens, you'll recognize the NPC). He will give you new clothing items. He wants you to bring specific legendary pokemon to him and he gives you themed clothing if you have caught them. They don't need to be in your party.
It doesn't seem like there is a style card, but I could be mistaken, I haven't caught all the legendary pokemon yet.
