The combination of light blue and orange is remarkably fresh. It's a color pairing you rarely encounter.
The fabric has body and substance, with a tactile quality that feels good against the skin.
The buttons are milk glass.
An embroidered tag is sewn at the neckline.
Subtle gathering is present at the neckline and cuff edges.
There is a missing second button and a small hole on the back, though these do not affect wearability.
If you've been searching for something like this, perhaps this is the moment.
