Disney Stitch hug Baby Yoda shirt, hoodie, tank top, sweater and long sleeve t-shirt
Just check which norm you mask is compliant with when you buy itThe cloth mask is supposed to go on top of medical version.

While I understand this pertains to medical professionals, many people will just see it as another excuse not to wear a mask.
