I think Frette (based in Italy 🇮🇹, made in Portugal 🇵🇹), Möve (made in Germany 🇩🇪), and Tekla (based in Denmark 🇩🇰, made in Portugal 🇵🇹) are good, but I’ve only looked at their towels. Lots of people online seem to like their bathrobes too though.

A lot of good European fabric stuff is made in Portugal 🇵🇹, so you could look for that too :D
