I ordered this as a gag... (long story, you don't need the details...)

Upon putting this mask on, it looked so REAL, it scared all my dogs, and when I looked in the mirror, I too nearly ran out of the house!

The mask is totally concealed if you wear a shirt having a collar. The material under the face of the mask fits nicely under the shirt, making for a seamless transition down to and past the neck as not to reveal the edge of the mask which might give clues it isn't real.

One word of caution, upon taking the mask off, I nearly gagged when it got caught coming off my head. This is a snug fit, and for me, I'll never don this mask again, unless someone is nearby who can help me remove it.
