His wife must be looking for it
This is yet another very creative solution, although I’m not sure what his wife thinks of him using her intimate clothes for this purpose. Hopefully, she isn’t looking for it. Brasiers are meant to provide support, and although this isn’t their original purpose, they surely provide him with mental, as well as physical support.
Since masks were ripped off the shelves, they became outrageously overly priced. It might be the social panic that’s finally getting to us, but this looks like a rather safe solution – it surely more filtration than the basic medical masks. The only problem, really, is that it seems like it might be hard to breath through all this padding.
