Hej! How to dress "Danish"?

Hej, I'm going to a party where you pick a country, dress as it and take food for it. I already know I'm going to make a selection of smørrebrød with plenty of smoked fish, remoulade, pickles etc. But I'm not sure what to wear! I don't want to have a full head to toe traditional garment because it's still a fairly casual thing, are there any design aspects or silhouettes I can incorporate instead? My dad lives in Denmark but I've only visited 3 times and we're not talking atm so I can't ask him 🥲
