We don't know what this onesie fad is all about, but celebrities really seem to love wearing these comfy, cozy and fashionably inept uni-suits.

Check out these pictures of stars wearing onesies, and let us know what you think of this "trend" (if you can even label a Snuggie-esque slip-on as a trend) in the comments below.
