Halloween costume ideas

Mikayla • I'm 23, married for 4 years, we have a beautiful 2year old little girl! she is our universe!!!! I'm a cancer in a home with two Capricorns!!!! Baby #2 due may 2019!
I'll be 31 weeks on Halloween this year. Any ideas on costumes for me and my husband? What was or is your costume??? My husband's mother milks cows for a living and her mom always joked and said she belonged to the milk man and my husband found this just as a joke to her but I'm not sold on it
