Chris has honestly admitted to wearing a fat suit (Toby was really larger than Chris is in actual real life in previous seasons, so the actor had to wear a prosthetic costume to look bigger or appear bigger), Chrissy has never worn a big or fat suit on This Is Us, although she was asked to wear one when she was on American Horror Story: Freak Show. Chrissy had just lost near about 100 pounds and was really "thrilled" to learn she wasn't big enough for her role as "Fat Lady" Irma Wiggles.
