The star captioned the post: "It's taken 19 years... but finally leaned into the mother/daughter matching dress movement."
Fans adored their look and commented: "Beautiful ladies," and, "absolutely gorgeous".World News Tonight anchor, David Muir, also chimed in and commented on his friend's post by writing: "Beautiful women, inside and out."
Amy has been waiting 19 years to twin with her daughter
Amy shares Ava - who is a performing arts student - and her sister Amy with her ex-husband Tim McIntosh.
She's been married to her husband, Andrew Shue, since 2010, and she's a stepmom to his three children too.
While the TV star doesn't often post about her children on social media, she made an exception on Ava's birthday in December with a heartfelt tribute to her firstborn alongside some never-before-seen family photos.
Amy's daughters have grown up so much
"To the first girl I fell madly in love with at first sight," she wrote. "Happy 19th birthday Ava Lou - I’m so proud to be your mama - and love celebrating the woman you are today and everyday!!"
When Ava was accepted at college, Amy couldn't help but gush about how amazing she is too.
"She was a performer at heart from the moment she entered this world - full of empathy and compassion," Amy shared on social media.
Amy's other daughter Annie is still in school
"She's always made me proud with who she is but it's incredible to see where she's going and what she will become!
"Her Noanie and I always knew she was a bright star in this world and my grandmother is cheering her on from up above - I can hear her happy tears now Ava - she is smiling from heaven saying way to go."
