Ships Pullover Shirt Tanguery Tunic Dress

This is a button-down pullover shirt from Ships.
The first image is the most accurate representation.
Length from the back of the collar is approximately 90cm.
Width under the arms is approximately 55cm.
Sleeve length is raglan, measured from under the collar, it is 64cm. For me at 158cm, it's just the right length for my wrists and knees.
It is 100% cotton with a thick fabric.
There is no size listed, but it is approximately an M size.
It's very cute with details like shoulder and side seams, elbow tucks, a reinforced accent with light blue stripes on the hem (longer in the front), gathers on the raglan sleeves, and shell buttons.
The button in the bottom left of the 16th image was lost, so I have replaced it with a similar button. This one is not a shell button, but it is the one in the bottom right of the 9th image. The thickness of the button is thin, but it doesn't look too out of place.
Purchased 3-4 years ago, worn about 5 times. I don't think there are any noticeable stains other than the button.
