Note her nose isn't full of mucus from this, so she seems to have a clean nose!
More safe sneeze in that case!

Anyway, I don't recommend to stay on the way of the sneeze blast... her release must be loud enough to hear from the safe distance. Holding the feather with a telekinesis is also a good safety measure

.
Also, whatever she is wearing, it looks lightweight and stretchy enough to allow her inhale the huge mass of air freely.
