Marilyn Monroe and Frank Sinatra Costumes

My children, Carter age 5, and Chloe age 3, are dressed as Frank Sinatra and Marilyn Monroe. The kids wanted to be "something different" so I started thinking of possible couples costumes. I have pictures of old movie actors/actresses in our basement and that's where the idea ultimately came from. I put together a suit for my son and purchased a hat online. The Marilyn costume was a bit more challenging. I searched for the real dress online to look at and, constructed the whole thing from scratch. I bought sateen fabric and ribbon. I really don't know how to sew clothing so I used an old t-shirt of my daughter's, and cut it to shape, then sewed the sateen to it...that way it had a lining too. Surprisingly it worked out! It did take 2 tries, I forgot to allow for gathered areas and seams so it was too small! So, once the outfits were completed I found a trench coat for Frank online, and sprayed his hair black. Marilyn's makeup was easy...lipstick and the mole on her face. The shoes were found at a thrift store.
