I have a few pairs of footed sleepers, but I've about worn them all out, I wear them so often! Where has everyone found these to fit an adult? I got three pairs at ShopKo a few years ago and they were great, but they don't seem to have them anymore. Don't want ones with buttons or drop seat or hoodies. Just good ol' babyish footed sleepers. Opinions anyone or ideas? online or store bought is fine.
