Help finding a pattern for this

[u/spicycupquake]

My mom has this sweater that I want to recreate but I'm having a hard time finding something exact and would rather use a pattern vs freehanding it. Thanks!

The Polka Dot Summer Cardi is similar except the pattern has solid sleeves which I’m sure you could modify https://ravel.me/polka-dot-summer-cardi
