The 43-year-old actress said she has difficulties finding suitable outfits for the festivities, reported Ace Showbiz.
"When I go shopping, most of the time I'm disappointed," McCarthy explains why she started a plus-size clothing line.
"Two Oscars ago, I couldn't find anybody to do a dress for me. I asked five or six designers - very high-level ones who make lots of dresses for people - and they all said no," she said.
'The Heat' star also talked about her marriage to husband Ben Falcone, who played the air marshall in 'Bridesmaids'.
"The important thing is our family and kids. I see teenagers or people who are 21 and think, I was an idiot at that age. I was running around New York like a crazy woman. Thank God I only had three and a half cents to my name. I was too immature to handle success then," McCarthy said.
