Before the trend was even a whisper, way back in 2019, I had some fun playing with versions of this look. For "shorts" I used my knee length sarong shorts, which look like a skirt from the front. For jacket, I wore my thrifted Paul Smith linen blazer, a much beloved summer item.
The day I wore this outfit I also tried on (in various stores -- I do not own jacket 2 and 3) what were then the new longer jackets so you can see how it looked with those. The proportions are not great for me and would have been even harder to manage with a completely flat shoe -- these sandals have a 2 inch heel. Even so, I didn't mind either look.
I will definitely wear the first version again this year.
