Honestly, your mileage will vary. As long as you're wearing some kind of mask, stores are unlikely to bother you. If you're required to wear a mask at work or school, you may want to choose a mask that's less obviously sheer. However, there are ways to work around this. Many people have reported success wearing a double layer chiffon mask that is close in color to their skin tone--so it's less easy to tell that the mask is see-through.
