Isoshima legendary bespoke shirt maker around since the beginning of aloha shirts.

Based on the collar style I’d date this to the late 40’s early 50’s.

The fabric is of high quality and a very nice tight weave. Nice details like the hand sewn buttonholes.

The shade of blue in person is lighter than the pictures, but darker than a sky or baby blue. Couldn’t find a Pantone match.

No size or content tags.

Measurements pit to pit and bottom of collar to hem are in title.
