She was super-curvy in her SNL appearance BITD. I still remember her spoofing then-popular diet maven Susan Powter... Stuffed into a leotard, her hips and thighs were huge. Her Showtime show Fat Actress is also worth checking out. It's not a good show on any level besides the fact a lot of the story lines are about her weight (see: title) and she wears some pretty daring stuff. Veronica's Closet starred Alley and another of my all-time fave plus-sized actresses, Kathy Najimy (who's since slimmed down, drat), but they always dressed the two of them in huge, flowy layered dresses that hid all the good stuff.
