Post O’Alls revisits one of their earliest patterns with a seasonal update to the No.1 Shirt MV, cutting it from a gauzy white cotton mesh built for the heat. Originally designed as a utilitarian outer shirt in 1993, this version strips it back to the essentials with clean lines, a single chest pocket, and a soft collar, all while keeping the functional proportions and coat-style front placket. The “Cool Mesh White” fabric is a lightweight cotton with a visible texture and open weave that breathes beautifully in warmer months. It wears almost like a hybrid between a shirt and a light summer jacket, making it easy to toss on over a tank, tee, or even swimwear. The silhouette is relaxed and square, with dropped shoulders and plenty of drape to give it that easy, lived-in feel Post is known for.

Fit Notes: As with most Post O'Alls fits, these are on the roomier side. Their shirts are meant to layer under the rest of the jacket lineup, but they're still big, so take that into consideration. We recommend sticking with your true size on this piece unless you want a more tailored look. Then go down once. Tommy is 5'10," 165lbs with a 40" chest, and is wearing a M in the pictures.
