Many onesies, be they for children or adults, are brightly colored, have silly patterns printed on them, or are even made to be more like costumes representing animals than like lounge-wear. If you like the comfort and simplicity of an adult onesie, but would rather not go for the wackier options listed above, you could get yourself a simple black onesie. Something warm and comfy to wear when lounging around the house in a color that does not draw attention to itself.
